Upgrading from 3.4.11...

[James Beam]

Are there any issues I should know about when upgrading from vpopmail-3.4.11 to the latest version?   I have a server that has been running for about a year now on version 3.4.11. I would like to upgrade it to the latest version if for no other reason than to have it consistent with my new server. It has about 3 dozen domains on it, and I do not want to interrupt mail service on those domains if at all possible.   I am thinking this is just a compile like I did the previous version and install it?   Thanks for any advice you folks can offer.   James Beam
