Is it possible to change the instance url after installation of the mastodon?
no, its create fedration issues other instance will see it as new instance
here is the discussion
@inditoot @Gargron Thanks for the information.
No network have good solution for this. Hubzilla/Zap is close but not perfect as they loose ability federate to other networks as far as I know.
The main Problem is updating other server which is main issue
mast.datamol.org is one server in the network
