I see WinSPM has the nice "convert" feature to go from different versions. I am having some problems getting a "board mismatch" error when attempting various upgrades. For example, I downloaded and converted an .ams file from a 6.1 CKE3, coverted it to 7.0 then attempted to restore it on a CKE5 R7.0 V14.0 and got the board mismatch. Must the CKE revision match? What are the general guidelines for upgrading?
