Ghost uninstall question

Running Win XP-Pro SP2  with Ghost 10 (also have Ghost 12 & 14 but saw no need to upgrade).

 

Question is if I need to use the Norton Removal Tool for NIS problems, I know the NRT will wipe out all Norton products including my Ghost 10 so:

 

1) How do I protect and save my current backups (restore points)?

2) If I elect to re-install Ghost 14 vs the old Ghost 10, will Ghost 14 be able to utilize the Ghost 10 restore points?

 

Thanks
