New DCs in ESS 600 from ESS 100?

Hi Friends,

I was wondering....

we are upgrading from NW04: ESS 100 sp19 to NW04s: ESS 600 sp12.

I noticed in the new version (ESS 600 sp12) there are new DCs that end in "cfg"

For example...

ess_usaddr~cfg

ess_uspdata~cfg

ess_usfam~cfg

etc. etc.

In the old version (ESS 100 sp19) these "cfg" DC's did not exist. Are they new configuration type DCs? Not sure.
