Installing Backup

Hi All,

I need to import UCS backup from an F5 VM which is running on ver15.1.2.1 to a new VM which is running on ver12.1.5.3.

Is it possible or I have to do an upgrade on new VM to make the version same on both?

I know that I need to take master key of the existing VM while importing the backup?

What should I do about the existing license in the UCS file --> running this command will work "load sys ucs no-license" or I have to run any other to command to make this work?

What other steps are need to import the UCS file successfully?

How to confirm whether the complete config is imported or not?

Sorry for asking so may questions, I tried searching for all these but no help.

Thanks,

Ashish Solanki
