Upgrade to 5.1.7: missing some files

Good Morning,

last week upgraded from 5.1.1 to thelatest version 5.1.7 as explained in the Upgrade document. After upgrade finished successfully i recognized that some custom files were missing in the new Docker container (for example some custom command line script located in libexec directory). Furthermore i recognized that Zenoss switched back to the old 5.1.1 container after rebooting the host.

So i have two questions:

1) What's the upgrade procedure for installed custom files so that they are available again after upgrading Zenoss version

2) What is the prefered way to make the new Docker container persistent.

Thank you,

Martin
