vCMP to rSeries Config comperision

One way to do it would be to compare the bigip.conf files of the old and new instances. I believe that file's found in the /config directory, and you can use a utility like Filezilla to retrieve it. A comparison utility like ExamDiff can then be used to show the differences between the two config files. You may need to rename the file, replacing .conf with .txt, if ExamDiff doesn't like it.

If you no longer have access to the old system, it's possible to extract the bigip.conf file from a ucs backup. Instructions for doing that can be found online (I've done it couple of times).

Good luck!
