Upgrading to 64bit

Hello all.

We have 32bit activated version of dss v6 lite running on 4 GB RAM (only 3 GB are visible). The problem is that once a month system cache becomes full. We are going to install 8 GB RAM and to upgrade dss to 64bit version. The question is: is it safe for data and settings (permissions, samba exports and so on) stored on the server? Should we rebuild volumes?

Thanking in advance.

you will not be able to see your current volumes if you change to 64 bit,
so it will be better to recreate new volumes

I would backup the data then change to 64 bit
resotre the data
