I currently have a SINGLE SERVER with the above setup BUT would love to make it into a Multiserver Setup With Dedicated Web, Email, DNS & MySQL Database Servers On Debian With ISPConfig it that possible or do i have to make a multi server from the get go
I would set up a new panel, let the other servers join as slaves, and then migrate using the Migration tool: https://www.ispconfig.org/add-ons/ispconfig-migration-tool/ As it’s currently not possible to easily move data within the panel (see https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/482)
