People have very kindly advised about RH6 to RH8 TOCs, May I also ask how does one handle indexes, are the index entries of a RH6 project kept when it's opened in RH8?
As always, make a backup of a project before you upgrade. We have a folder with the zips of all our projects before upgrade.

Just tried opening a project which had an index (proj backed safely up first!) and it worked.
