Upgrade Experience | CMAPI doesnt load old cmapi_server.conf after uninstall

After uninstalling and reinstall cmapi as said in documentation
https://mariadb.com/docs/operations/upgrades/upgrade-multi-node-from-5-to-6/#uninstall-the-old-version

Actual
cmapi_server.conf configuration is lost because cmapi_server.conf.rpmsave isnt loaded. Thus there is no x-api-key and curl calls fail.

Expected
When upgrading cmapi my cmapi_server.conf shouldnt be replaced with the default. My existing x-api-key should exist

post install you see the byte size difference
