Hello all -
We have a client with an existing Exchange 2007 system and we introduced Exchange 2013 into the mix. Since then, we have had nothing but issues with the coexistence of Ex2007 and Ex2013. I just got off yet another call with MS and their final recommendation was to uninstall ex2013 and reinstall it. I am of the mindset at this point to simply remove 2013 and not go back to it right now. Rather, I am thinking of putting 2007 (or 2010) in its place.
Note - Upgrading the existing 2007 server is not an option right now so Ex2007 will continue to exist in this environment for another year or two.
Since this Ex2007-Ex2013 coexistence has been so troublesome, my question is how difficult will it be to just remove Ex2013 and replace it with Ex2007 (or 2010)? I can do the add\remove programs thing easily enough (I hope) but will there be left over pieces of 2013 that will hamper me moving forward?
If you have any thoughts\comments, please hit me with them.
