There are very good manuals online for deployment, upgrade and migration of servers. In my experience, I had no issues at all. Compared to other collaboration/email servers, including Microsoft Exchange and Lotus Domino, I classify IceWarp as one of the easiest to deploy.

The deployment, and the version updates / upgrades, are straightforward and with no issue. Even the initial conversion from 602LAN SUITE happened overnight.

IceWarp is always ready to help. When there are big changes pending, we always contact and discuss them first to avoid issues.
