HPDM change Master Repository to be on a NAS

Hello!

We use HPDM to manage our Thinclients. 

It runs in a little VM, and the images that we pull from the Thinclients eat up all the space there on C:\

So we wanted to change the Master Repository to be located on a NAS.

We already have managed to have a Share as additional repository on that NAS.  But its not the Master one.

How can we change that?

We want the Master Repository to be on the NAS, so the VM where HPDM runs doesn't have to contain all those big Thinclient images.

HPDM version is up to date.

Thanks in advance!
Regards!

ND.
