Media and images movement from old master to new

Hello Geeks !

We have one old master server running on 7.5.0.6 and we no longer using it to take backups ,it used to backup on 4-5 clients and have like 500 odd media in its EMM.

Now our new master server runs on same OS solaris X64 and netbackup 7.5.0.6 ,what I am looking for is to move the consolidate the images of clients on old master server to new master server.

I will copy db/images of clients from old master to new master and vmadd all 50 media ? 

Questions here are:

1) would the media expire on their due data if i simply vmadd in our new master?

2) do i need to create the volume pools that were in the old master or can simply put them in any read only volume pool as we don't intent to use those media for backups .

PS: We are not looking to import all the media.

Please advise.
