Avast V8 to V9; Backup Settings Restore Work ?

I’m looking to try one of my non-critical PCs from 8.0.1497 to V9…W7 64bit based.
I may do a GUI update for do a full uninstall and clean install.
If I do the clean install and previously save/backup my xxxxxxx.avastconfig file can I “restore” in V9 ?
Something tells me that this config file would not be compatible from V8 to V9 but wanted to check.

Thx.

Yes, the config file can be imported from the older version.
