Pgbackrest changing RepoServer to new one

List,

I am in need of changing Repo Server of an existing working pgbackrest
setup(RHEL 9.3 , pgbackrest 2.52.1 database version 16)

*I have googled, got the information that I need to do *

1. First shutdown the Postgre Server cluster/instance. ( This is a
production server, downtime permissions required if need to do so)

2 stop the stanza and delete the stanza

3. Then recreate the stanza with the same name from the new Repo Server.

In need to change the RepoServer due to the storage limitations on the
RepoServer forced to move to a large Repo Server.

Can I bypass the step1 ( shutdown the postgreserver ?) and do step 2 and
step 3, will this action stalemate the entire DB server and backup setup.

Request your valuable guidance and advice.

Thank you,
Krishane
