Hello,
There are improvements to the installation/upgrade process in the Content Server 16.2.4 release. Modules must be reviewed for compatibility, so I am sharing a powerpoint presentation with an "Installation walkthrough" for more details and how to test it.
Also, this presentation highlights a few things that your module should NOT implement in order to be compatible with future changes that we are currently working. If you module follows under any of these categories, please contact us so we can discuss the best solution for you.
Cheers
Juliano Ghisi
