Copy configuration from very old hardware/software to new hardware/software

Thank you for your reply!

I got the configuration imported by removing anything related to certificates and then adding it again successively (to find out which part of the configuration caused the error).

Now I'm trying to do the same thing on a virtual device. Using an archive ucs-file from the virtual device I've created a new ucs-file containing the necessary configuration from the running devices and imported it on the virtual device. No errors. But after importing the configuration the virtual device started complaining about the license. So I re-licensed it. But that resulted in the big-ip reloading the configuration over and over… Anything you recognize?

Log says: "The allow_dynad policy boolean was changed to on by root Configuration reload request received, reloading configuration"

(over and over again approx. 2 times per minute)
