I am using these 2 commands for migrating accounts from server 1 to server 2 (both in the same version) :
/opt/zimbra/bin/zmmailbox -z -m email@example.com getRestURL “//?fmt=tgz” > /tmp/account.tgz
But now I want to use the same method for a 'update' operation on the same server for a test from version 5.0.18 to 6RC1
/opt/zimbra/bin/zmmailbox -z -m firstname.lastname@example.org postRestURL “//?fmt=tgz&resolve=reset” /tmp/account.tgz
But it seems that the tgz file resulting in the backup on version 5 in not compatible with tgz for version 6 ???
As I can't use imapsync, what other tool I can use ?
PS : sorry, but this post should be in the 'Migration' forum.
