We have a domain migration starting very soon and I wanted a little information about reusing site codes
child.lab.local - Current domain with SCCM 2007 environment
lab.local - Root domain we are migrating to, going to implement SCCM 2012
SCCM2007 servers
Site Code: AAA Server name: AAASCCM01.child.lab.local
Site Code: BBB Server name: BBBSCCM01.child.lab.local
SCCM2012 servers
Site Code: AAA Server name: AAASCCM02.lab.local
Site Code: BBB Server name: BBBSCCM02.lab.local
Do you know if I can reuse the site codes for the new SCCM servers in the root domain? Or will I have to change them to avoid any conflicts?
