As with any move to a new version, you should make backup copies of your VIs before saving them in LabVIEW 8.0.
Warning: There is a feature in LabVIEW 8.0 that saves an entire hierarchy (File>>Save As>>Duplicate Hierarchy) but it does NOT work for opening VIs from a previous version and saving copies for 8.0.
Duplicate Hierarchy will save the original VIs before making a copy. It is useful for distributing a copy of your 8.0 VIs, but it does not work for migrating VIs to 8.0.
To migrate VIs, make copies on disk or use "Save with Options" in your previous version of LabVIEW. "Save with Options" does not exist in LabVIEW 8.0.
