They should upgrade fine – just make sure that you have a backup copy made in case anything goes sideways ;>)
Test out a copy of your RH 7 projects on a trial copy of RH11 to experiment.
Just to add, after you upgrade from RoboHelp 7, run the Tools > Update
DHTML effects in topics option. This is required because RoboHelp 7 has
a different topic structure than later versions.
Also, during upgrading from RoboHelp 7, I have encountered the error
that .apj could not be found or openend. This happens on
legacy projects created prior to RH7. If you encounter this, here's how
to fix it:
- Remove the project and restore from backup.
- Create a new, blank project in RoboHelp 7.
- Copy the missing file from the blank RH7 project into your project.
- Try upgrading again. It will work fine now.
