So is rsyncing twice (once with the "old" zimbra server up and once with old zimbra server down) works without causing any issues? I'm actually more interested just in the index and store if that makes a difference. We have an old slow SAN and we want to migrate our data store and index to the new SAN but its going to take a *long* time....and we'd like to not have to have zimbra down the whole time. We're wondering if doing a live rsync to get the bulk of the data copied over while zimbra is still running and then shutting zimbra down to run a final cold sync and then switching the mount points is safe.

I've seen lots of other posts with rsync but they all talk about it with zimbra shut down. This is the only one I've seen talking about doing it this way.

Thanks.

Hi,

This is my tested doucument which I have posted and done at my level, withour any issue.
Yes you can done rsync twice in any condition without any issue.
Use the correct command which I have write on forums.
after all your backup is come on on another server, which U want to make Live. you have need just a max. downtime of 15 min to again rsync on live server.
when again rsync is done, you can easly live the server without any issue .. with my below documents.
issue regarding index, and store it will now make any issue,. because I have build this evironment around 10time without any issue and live also.
