DNS record for migration between server

Nextcloud version (eg, 20.0.5): 22
Operating system and version (eg, Ubuntu 20.04): Debian 9
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4
PHP version (eg, 7.4): 7.4


i want to migrate a nextcloud server and following the process in the nextcloud documentation it is expected that the domain name is a CNAME and to just edit the value.

My domain record is a A record.

Technically this should not change anything during the migration, I remove the A record, create a CNAME, wait for propagation and voilà, but I wanted to be sure so I made this post to see if anyone has ever encountered a problem with a migration using A records.


No need to worry about A record. Once you are ready to change the server just adopt the IP address of the A record.

The idea behind the CNAME is that you can run (e.g. test) both servers in parallel using using their real A names… while CNAME is a well-known and maybe better sounding name like cloud.mycompany vs server432.hosting
