We are currently using nexus repository version of 3.15.2 and we are planning to upgarde to latest version ( 3.62 ).
Do we have any documents we need to refer to perform upgarde ? Or what are the prerequisite checks i need to take ? and what are steps to perform this upgrade ?

We have a page in the help site that should have the information: Upgrading a Standalone Instance
