OK. Upgrades should work fine when following: https://github.com/kaltura/platform-install-packages/blob/master/doc/install-kaltura-redhat-based.md#upgrade-kaltura
Of course, if something does go wrong, you're always welcome to report it and I'll gladly help you resolve it.
That said, you can also choose to install 10.2.0 on the target server. That can be done by changing /etc/yum.repos.d/kaltura.repo on the target repo and replacing 'latest' with '10.2.0'.
