The issue: in screen of Resync Tool there is a service drop-down list to be selected. I need to select an old IspConfig server and sync it into new installed IspConfig server How to add service item in the drop-down list?
The resync tool is a way to force-write the config again on a server. It's not a function to move config between servers.
I would like to import all mail boxes and their content to new installed IspConfig server How to do so?
Are the new and old server 'separate' systems or are they connected as slaves to the same ISPConfig master? if they are separate systems, then you can use the ISPConfig Migration Tool to import email and config into the new system. https://www.howtoforge.com/tutorial...-confixx-plesk-to-ispconfig-31-single-server/
