Dear Laurenz Albe
Our application for reporting is dependent on the replica node for handling read-only operations. If we proceed with the proposed changes, it would result in a one-month application downtime, which would significantly impact our operations and is not a feasible option for us.
We would greatly appreciate your insights and support in identifying alternative solutions to minimize down time (one month)or another solution alternative for rebuild replica from scratch. Your expertise and advice would be invaluable in helping us navigate this challenge effectively.
Thank you for your time and assistance.

No, that won't work.
You have to upgrade the primary, then rebuild the standby with
"patronictl reinit". There is no safe way to upgrade the standby.
