Upgrading this old Rel. 8 to latest and greatest MCD 6. So I'm going from R8 to MCD 4, do the Migration Checklist, then going to MCD 6. I've heard differing views on whether to use the MCD 4 SI tool from R8 to MCD 4 then use the latest SI tool for the MCD 4 to MCD 6 upgrade as opposed to just using the latest SI tool to do both upgrades. What's best as far as you're concerned ? thanks
