The current version which we use is GeoServer 2.10.0, which is a platform-independent installation. We want to upgrade this version to near latest version 2.19.x or 2.20.x. The plan is to take backup of data_dir of 2.10.0. Install a new version on a different port, test it with old version data_dir, if all OK, uninstall 2.10.0 and install the new version on the required port again.
Is it recommended to Jump from 2.10 to 2.19/2.20? Are there any major concerns to keep track of? Is there a better plan to upgrade/ Jump from 2.10 to 2.19/2.20?
