Thanks for the quick reply but I am still a bit confused. You said yes to both questions which covers the first one OK, but on the second one I asked actually in two parts. I asked if I needed to delete ST6 before upgrading or will the upgrade overwrite the ST6.
Now I am assuming (which can at times be a problem), that in your answer of yes you were saying that the upgrade does overwrite the ST6 and not saying - yes it is necessary to delete ST6 before upgrading. Is this correct?
Yeah, sorry for the too brief reply.....you cannot have two versions [installations] of Solid Edge on the same machine, so an uninstall of the previous version is required.
Further, if you have customised templates, or hole/material tables thesecan be transfered also, but you will need to manually copy these, and replaqce them in their relevant directories after upgrading.
