Hello everyone,
I'm currently working with Carbonio CE and I'm looking for the best way to migrate a complete instance from one server to another, simply and reliably.
Context:
Old Ubuntu 22 server: already in production (existing accounts, emails, and configurations)
New Ubuntu 24 server: clean, ready to receive Carbonio
Objective: migrate all data (accounts, emails, configurations, etc.)
My questions:
Is there an official or recommended method for this migration?
Is it better to:
restore from a backup?
or use a synchronization tool?
What are the key steps to avoid data loss?
Are there any sensitive points (DNS, certificates, permissions, proxy…) to monitor?
If anyone has already done this migration, I would appreciate any feedback or a step-by-step guide.
Thank you in advance for your help.
Why don't you just upgrade Ubuntu to 24? Is there a specific reason for?
I first updated Carbonio CE
Then I upgraded Ubuntu to v24.04LTS
Then I excuted the update proces of Carbonio CE
Took me al together 1,5 hour and all works well.
I encountered too many conflicts during the upgrade; I'm really at my wit's end.
