migration NLB to new
Posted on 2012-08-28
There are two Windows NLB clusters.
Win NLB cluster 1 with 2 nodes (CASHUB01 & CASHUB02) with CAS Array (= Array01)-->OLD platform
Win NLB cluster 2 with 2 nodes (NewCASHUB01 & NewCASHUB02) with no CAS array-->NEW platform
The 2 Win NLB clusters are in same organization and in same AD site, so this the reason why there are only 1 cas array.
The 2 old Win NLB cluster HW nodes are end of life. These will be decommissioned after last mailbox move to the new HW mailbox servers (the new MBX servers are also in same organization) and also the old cas array must be removed due too much problems.
Currently after installation of the 2 new CASHUBs these nodes were automatically added in the CAS array (there are now 4 present; 2 old & 2 new).
The new DB's on the new HW MBX servers are pointing automatically to the existing Array01.
My question is what is the best way to switch from old Win NLB service to the new one?
Can someone correct the list below please?
1 - remove the old cas array (= array01)
2 - set new cas array (=arrayNEW) and name of the new Win NLB VIP
3 - point all already created DB's to the new array
4 - normally outlook should automatically change the Exchange server name in their profile
5 - if mapi profile isn't updated --> update this with script or GPO
