We have EPiServer CMS 6.0 on our server.
Now we want to move an EPi CMS 5 R2 SP2 site to the same server.
Will there be any problem installing EPi 5 R2 SP2 on the same machine as EPi 6?
Mmm not sure about that order Jenny. I've run CMS 5 SP2 then CMS 6 after installing in that order but not the other way round. Best advice would be to try it on a dev machine first.
Agree with David. You should especially test your scheduled tasks after installing CMS 5.
