I did an erase-and-clean install of 10.3. After installing Microsoft Office X (and all of its updates through 10.1.5), I dragged over from my other drive the entire OS 10.2.8 Documents folder and, effectively, replaced the Documents/Microsoft User Data folder created by the installation of MS Office. Before I had an external drive, I simply went into my Retrospect backup set and marked for restore Documents/Microsoft User Data folder.
A trick I learned for those times when one has to do a clean install or just re-install Office without going through the pain and tedium of doing a lot of extra work:
- In Document/Microsoft/User Data, alias my custom dictionary, personal templates and Word "Normal" files.
- The custom dictionary alias I move to my Library -> Preferences -> Microsoft folder to replace the one created by installation of the program.
- The aliases of the rest I move to Applications -> Microsoft Office -> Templates. I move the personal templates into the subfolder "My Templates." The "Normal" alias from Documents replaces the "Normal" file in the full Templates folder.
[robg adds: I couldn't find the "MVP and FAQ pages" on the Microsoft site, but this page is the main support page for office v.X. When I upgraded my machines, I just dragged my fully configured Office v.X folder from my backup to my upgraded box, along with the Microsoft user Data folder, and all was good to go...]
