The network edition of zimbra supports a feature we use called zimbra archiving and discover (ZAD) - outlined at https://wiki.zimbra.com/wiki/ZAD .
I have a NE server running ubuntu 12.04 and zimbra 8.6.0 (with zextras legacy suite installed) that I was hoping to migrate to ubuntu 16.04 and 8.8.8 without a lot of downtime, but I'm running into problems and I think they may be ZAD related.
If I try the import wizard on 8.8.8 it shows the domains but won't show any accounts despite my knowing they are in the source backup. Not sure if 8.8.8 import is totally broken or just broken because the source accounts have ZAD?
If I try the import wizard on 8.8.7 is shows the domains and will let me pick the accounts from domain.com - but unfortunately not the domain.com.archive accounts.
Does the export/import stuff not currently support ZAD currently? I really like it otherwise!
