How To Use Imapsync To Migrate Google Workspace To Carbonio | Carbonio CE

In this article, we are going to discuss about the migration process of your email system from Google workspace to Carbonio CE. To perform this migration process, we are going to use Imapsync (a free, open source tool). In another imapsync related migration article, we have discussed how imapsync works. But for your convenience let’s take short overview of how imapsync works and it’s configuration.

Imapsync can’t migrate Contacts, Calendars, Tasks nor Chat messages. Imapsync only migrates email data.

Working with imapsync

Imapsync works in a simple way. It pulls data from old server and then push it to the new server.

Important Fact:
Imapsync can’t migrate Contacts and Calendars.

You can get tons of articles on the internet about how to install imapsync server. To make it more convenient for you, I am sharing a sample imapsync installation steps.

You can check out this article where we have used containerized imapsync without getting into the hassle of installing it or using any third server.

  • To proceed with this phase you need docker in you system. If your new system comes with a pre-installed docker then it’s fine or you can install it on you own. For example:

If your system does not have docker installed, then while executing next command you will get this error:

root@mail:/tmp# docker pull gilleslamiral/imapsync
Command 'docker' not found, but can be installed with:
apt install docker.io
root@mail:/tmp#

Then, you can just install docker using onscreen help.

root@mail:/tmp# apt install docker.io -y
  • Now install imapsync using the docker container.
root@mail:/tmp# docker pull gilleslamiral/imapsync

Status: Downloaded newer image for gilleslamiral/imapsync:latest
docker.io/gilleslamiral/imapsync:latest
root@mail:/tmp#

Important Note:
Using docker image of imapsync is a smart and convenient way of using imapsync. Let’s take a look at some of it’s benefits:

1. You do not need a third server to install imapsync which reduces the dependency on third server and removes all other factors that can affect your migration process (i.e. interconnection between source server – imapsync server – destination server)
2. You do not want to install the imapsync server into either of your servers (Source or Destination) as it can jeopardize your server configuration.
3. When you are using the containerized version of imapsync, then you do not need to take any hassle to install and configure the imapsync server.

Note:
If you don’t have the credentials of a global administrator you have to create it on the source server. Now, do a test run before executing a massive sync process. Imapsync supports delegated auth login (--authuser1, --authuser2), so it is possible to migrate accounts even without knowing each individual users passwords (using a global administrator credentials).

Preparing Google Workspace Account For The Migration

There are few things you need to do to prepare your account for the migration.

  • Go to your google account’s Security option from Manage your Google Account.
  • Turn on 2-Step Verification.
  • On the bottom of 2-Step Verification page, create an App passwords for your imapsync.

Preparing Carbonio CE Server For The Migration

  • Collect all email addresses from Google Workspace and create them on Carbonio CE.
  • Collect all email accounts password or reset them temporarily.

Migrate The Service From Old Server To New Server

We need to migrate the service from old server (Google Workspace) to new server (Carbonio CE) by changing the MX record. As soon the mail stops landing to the old server (Google Workspace), we will start the data migration process using imapsync.

Initiate Migration Process On Imapsync

Write down that imapsync script for each account and recheck them. For example:

docker run --rm gilleslamiral/imapsync imapsync --host1 imap.gmail.com --user1 msilsa26112@gmail.com --password1 usndoemfjdteskd --host2 192.168.1.91                             --user2 sharif@example.com --password2 123456

So let’s execute our script on imapsync server:

docker run –rm gilleslamiral/imapsync imapsync –host1 imap.gmail.com –user1 msilsa26112@gmail.com –password1 usndoemfjdteskd –host2 192.168.1.91 –user2 sharif@example.com –password2 1234561

Important Note:
Imapsync supports delegated auth login (--authuser1, --authuser2), so it is possible to migrate accounts even without knowing each individual users passwords (using a global administrator credentials).
For example:

./imapsync --host1 imap_server/IP --user1 old_email_address --authuser1 --password1 auth_user1_password
--host2 imap_server/IP --user2 new_email_address --authuser2 --password2 auth_user2_password

As you can see already our Carbonio CE server is receiving messages from old Google email account.

But the imapsync process is not finished so, we have to wait to get all of our emails.

Meanwhile, if your imapsync server and Carbonio CE server can handle the load of multiple scripts you can run multiple scripts at the same time. But keep an eye on them so you know if anything goes wrong.

Our imapsync process completed.

Good! SEARCH ALL works on both accounts.

Folders sizes before the synchronization. It can take some time. Be patient.
You can remove foldersizes listings by using "--nofoldersizes" and "--nofoldersizesatend"
but then you will also lose the ETA (Estimation Time of Arrival) given after each message copy.

There is an interesting findings in the log. That is imapsync migrated all emails successfully except 8 emails due to their excessive size. And the log also hints what this error means with this link: Read https://imapsync.lamiral.info/FAQ.d/FAQ.Messages_Too_Big.txt or you can just increase your destination server message size limit to not get this error.

By looking closely, you can see the details of these messages and can take care of them.

Also, you can check migrated emails status from the user webmail in Carbonio CE.

Download User Data(Contact, Calendar) From Google Workspace

Visit takeout.google.com using the respective user account.

Select mail, Contact(*.csv format), Calendar(*.ics format) to download these data. Upon proceeding to the next page you will get few options like below image: (You can modify the options as per your preference)

Click Create export to start the exporting process.

As you can see in the Export progress, you will receive an email with your export data.

Now download, extract and upload the *.ics & *.csv file in your Carbonio CE server. After uploading the data to Carbonio CE server also modify the permission so that it can used by zextras user in future scripts.

Important Notes:

Few things you should keep in mind before starting the mailbox export/import process:
1. Set the socket timeout high (i.e. zmlocalconfig -e socket_so_timeout=3000000; zmlocalconfig –reload)
2.  Set Public Service Host Name & Public Service Protocol to avoid any error/issue like below one

root@mail:~# chown zextras:zextras /tmp/Contacts.csv
root@mail:~# chown zextras:zextras /tmp/Calenders.ics
root@mail:~#
root@mail:~# ls -ll /tmp/*.ics /tmp/*.csv
-rw-rw-r-- 1 zextras zextras  9119 Jun  9 16:54 '/tmp/Contacts.csv'
-rw-rw-r-- 1 zextras zextras 14105 Jun  9 16:54  /tmp/Calenders.ics
root@mail:~#

Upload the contact(*.csv) and calendar(*.ics) to the Carbonio CE server.

zextras@mail:~$ zmmailbox -z -m $i -t 0 postRestURL "/Contacts?fmt=csv"  /tmp/Contacts.ics
zextras@mail:~$
zextras@mail:~$ zmmailbox -z -m sharif@example.com -t 0 postRestURL "/Calendar?fmt=ics"  /tmp/Calendars.ics

You can also use bash script to import contacts and calendar.

#!/bin/bash
# User Account Contacts & Calendar importing Script

echo -en '\n'
echo "Starting Uploading Contacts & Calendar for all users"

echo -en '\n'
echo "Starting uploading Contacts & Calendar of all accounts of example.com"

echo -en '\n'
for i in $(zmprov -l gaa example.com);do zmmailbox -z -m $i -t 0 postRestURL "/Calendar?fmt=ics"  /tmp/$i.ics; echo -e "Finished uploading Calendar of $i"; done
echo -en '\n'
sleep 1

for i in $(zmprov -l gaa example.com);do zmmailbox -z -m $i -t 0 postRestURL "/Contacts?fmt=csv"  /tmp/$i.csv; echo -e "Finished uploading Contacts of $i"; done
echo -en '\n'

echo "Finished uploading Contacts & Calendar of all accounts of example.com"
echo -en '\n'
sleep 2

echo "Finished Uploading Contacts & Calendar for all users"
echo -en '\n'

Now your Carbonio Ce server is ready with all previous data (email, contact, calendar). BTW, you can download your other useful data (i.e. Drive etc) from Google workspace and upload them to your Carbonio CE server.

Preparing Carbonio CE Server For The Migration

  • Create all required users on Carbonio CE.

Let’s Do a Quick Check

Initial State of Carbonio CE

We need to migrate the service from old server (Google Workspace) to new server (Carbonio CE) by changing the MX record. As soon the mail stops landing to the old server (Google Workspace), we will start the data uploading process using script.

So right now, my test account (sharif@example.com) is in this condition:

zextras@mail:~$ zmmailbox -z -m sharif@example.com gaf
        Id  View      Unread   Msg Count  Path
----------  ----  ----------  ----------  ----------
         1  unkn           0           0  /
        16  docu           0           0  /Briefcase
        10  appo           0           2  /Calendar
        14  mess           0           0  /Chats
         7  cont           0           2  /Contacts
         6  mess           0           0  /Drafts
        13  cont           0           0  /Emailed Contacts
         2  mess           2           3  /Inbox
         4  mess           0           0  /Junk
         5  mess           0           0  /Sent
        15  task           0           0  /Tasks
         3  unkn           0           0  /Trash
zextras@mail:~$

After the Migration

So that’s it.
