Out of the box PA-500 steps taken,
1. down graded version to 4.1.10 successfully.
2. under device -> setup -> management, i changed the management interface IP, and on commit I get the following error.
invalid configuration. Schema verification failed.
profiles -> decryption unexpected here
Did some searching on support but could not find something that relates to the above error.
If this is going into an HA you could export the config from the HA existing member. Then import into the newly downgraded one replacing the version 5 config.
Now just change the node specific stanzas from here before commit.
