Upgrade and consolidate from 5.0 to 6.5 - Help !!

Hi,

Here's my current set-up:

 

 2 x Netbackup v5.0 Master/Media servers - each backing up themselves and a number of clients. we have two major data centres and I have one NBU server at each.

 

I have some business and technical drivers now to move to latest version of NBU, but also to create a more 'sensible' environment ( the media managemennt is messy with the current set-up, as media is moved off-site form each primary site to the mirror site, and I have concerns about media cross-contamination between the two environments)

 

Here's where I want to get to:

 

1 x Netbackup 6.5 Master/media server + 1 additional Netbackup 6.5 media server at 2nd site

 

 

I also have some concerns about the stability of the underlying O/S of one of the servers, so would like to do a clean build rather than an upgrade if possible.

 

So here's my stumbling blocks:

 

1) I can do a clean build of NBU6.5 no problem, but cannot import my NB5.0 Catalogs due to the catalog format change - is there a standalone method to do the conversion, or will I have to upgrade then rebuild?

 

2) Is it possible to combine my existing 2 catalogs into 1 and bring all my media into one management environment? - I'm not too concerned about being able to retain all my policies and settings etc , I can manually recreate these if necessary, but obviously would like to retain my existing media catalogs.
