How to transfer Linux email and "Horde" data to new server?
 

I hope this is the correct forum for this...

Hi everyone,

I'm switching to a new VPS provider and am looking to transfer all my data over. While I have no trouble moving databases and files in Linux, I'm not quite sure how to transfer pending emails (not yet downloaded from server as well as pending but not yet sent) and Horde-based email accounts to the new server.

Is it is simple as copying a particular set of directories? Both VPS providers should be on roughly the same version of Plesk which is what I'm using as a control panel. If it is this simple, how would I download the appropriate files from my old server and place them on my new server? SSH? A global administrator FTP account?

Is email somewhat similar across Linux servers?

Any help would be greatly appreciated. At this point I just want to make sure no emails are lost and that I can make a smooth transition by copying all email related items over.

Thanks,
- Matt.
