I'm doing an initial migration by following: http://wiki.zextras.com/wiki/ZxBacku...ZeXtras_Backup
Here's the scenario.
Old server: ZCS 7.2.0 100 accounts on domain.com
New server: ZCS 8.0.6 100 accounts imported from old server
Here's what I've done so far:
1.) I ran the Zxmig to export all of the accounts/items/etc to /opt/zimbra/backup/migrations
2.) I ran rsync on the old server to transfer to the new server: rsync -azvv -e ssh /opt/zimbra/backup/migrations/ root@mail.newserver.com:/opt/zimbra/backup/migrations
3.) I ran ZxBackup to import all of the accounts/mail/etc.
It's almost done as we speak. So here are my questions as I'm approaching switching over the MX record/mail flow to the new server:
1.) Do I keep the existing /opt/zimbra/backup/migrations data on the old server and run ZxMig again tomorrow when I need to update? Will this overwrite everything or just export the changes since the last ZxMig?
2.) Once I do another ZxMig I plan to rsync everything over again. It's my experience that rsync will add the files/items that were missing to the target/new server. Should I keep the /opt/zimbra/backup/migrations on the new server or delete it before I rsync?
3.) When I do my next restore on the new server using ZxBackup will I have to worry about duplication or any other problems? Or will it simply pickup the changes?
I've read through the incremental migration wiki thoroughly but I just want to make sure I'm not missing anything. I plan to switch the mail flow tomorrow and don't want any hiccups.
Please let me know if something is not clear or if you need more information!
