[Users] Zimbra mailbox project

[Barry de Graaff]

If you could make a tool to do an integrity check on zmmailbox exports, that would be really 
nice. It would also maybe allow the bugs in zmmailbox to get more specific, and we can 
than add debug info to the bugzilla. 

And maybe start hoping for a patch. 

Kind regards,

Hi Marc, 

As a Zimbra BSP, we're solely using Zimbra Network Edition here, but if I recall correctly, I think Barry is right. Zmmboxmove is included only as a Network Edition feature, while zmmailbox is included in both Zimbra versions. 

Thanks for the heads-up on the bug for the REST interface in Zimbra. I too have encountered that same bug in the past when doing an export/import of customer mailboxes from earlier Zimbra versions, which initially led me to stop using the import/export feature for customer migrations. I also ran across this list of known issues that Jorge posted for zmmboxmove around the same time as when bug 101760 was posted: https://wiki.zimbra.com/wiki/Zmmboxmove#Identified_Support.2FKnown_Issues . 

I'm going to experiment with zmmailbox, along with zmmboxmove to see which of the two can reliably move an end user mailbox in the shortest possible time while maintaining complete integrity of the source mailbox. If both utilities prove reliable in 8.8.6, then I could build the automation script for this project to simply check which utility is available, depending on which Zimbra edition is in use. Or, if neither works reliably (or with acceptable performance), then it's back to the drawing board to find or build a new option. The Zextras modules are definitely on the table as an option too.

Hi Randy, 

Is zmmailbox available in FOSS - I'm unfamiliar with FOSS, so don't know. You also need to be aware of this bug https://bugzilla.zimbra.com/show_bug.cgi?id=101760 which is pretty nasty and, I think, renders zmmailbox exports unreliable. I was just thinking that it might be that you'll be forced to leverage Network Edition features to make this project viable and in which case, you might consider the Zextras modules - in particular the migration component which may offer you more options and better performance. 

Cheers, 

Marc
