Hello,
I'm in final phase of decommissioning EX2010 after migration to EX2013.
I decided to do mailflow change as the last step.so this is what I have now:
2x HUB/CAS 2010 (WNLB) in the same AD site as 2x MBX/HUB/CAS 2013 (DNS RR)
2x EDGE 2010 subscribed into the AD site where all servers are
Current external mail flow if from MBX2013>HUB2010>EDGE2010 > Internet and via versa.
I would like to ask for advice how to switch to:
2x MBX/HUB/CAS 2013 + subscribed EDGE 2010.
Following TechNet, EDGE can be subscribed into EX2013 in case that there is only EX2013 in the same AD site.
so, logically, I have to remove the HUBs 2010 first before new EDGE subscription which break current mailflow.
where I need a help, is what should be the proper steps to achieve my goal ?
My idea is:
- create new send connector on EX2013 to EDGE 2010 manually
- remove edge subscription from AD site
- remove hubs 2010
- create new EDGE subscription and subscribe EX2013 as it should be the only EXchange in AD site
- remove/disable manually created connectors
would it work or is there any pitfall ?
thanks for any advice
