I have a server with 5.0.5 open source edition in a centos 5.0. Both binaries are x86.
Our server was upgraded from 2 GB RAM to 8 GB RAM. And our user base was also incremented.
Reading the performance optimization page at:
Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki
I found the recomendation to move from x86 to x86_64. So some questions arise:
a- how to perform a backup of mail settings and mailboxes in the x86 version than can be restored to the x86_64 version?
b- I went from 500 to over 3k users, single domain. Will I really benefit moving to x86_64 in this config? (performance/stability)
your suggestions are welcomed, specially in the backup/restore part.
