I want to join three ispconfig servers. They all run the same software base etc (Services (nginx, mysql, pureftpd, dovecot, (different php versions but as fpm))) with ispconfig 3.0.5.3 I found no where infos on how to join existing configs to a master server. They all should keep theire existing panel but be managable by every panel Is there a chance to achive this?
You can not join them, the records in the databases have conflicting ID's. For example each server has a website with ID 1, a mail domain with ID 1 etc. but the ID's have to be unique in the cluster.
