You will have to Import information from the other cell maangers into the New Cell Manager. Unfortunately, this is not something DP does very well
You can either import the actual physical media into the new cell maanger, or create a MCF file on the original cell manager, copy the file to the new cell manager, and Import the MCF file. IMporting the MCF file will take pretty much the same amount of time as importing the tape media
You can find the Export and IMport command for MCF files in the Command Line Interpreter (CLI) Guide in the synopsis for 'omnimm'
Before doing this, you may also want to run the command
omnirpt -report media_list_extended -no_protection -tab -log C:\temp\medialist.com
You may use any destination you want for the '-log' argument. This will tell you what media is no longer protected, it makes no sense to try and import this media or corresponging MCF file
