Yes you shouldn't have any trouble restoring from a backup that was done after you installed 8.1
The way I done the 8.1 update was as follows.
Hard reset my phones while they were on 8.0
Downloaded the "Preview for Developers"
Installed 8.1
Another hard reset
Then I set up my phone as new, going to the store and downloading all the apps I previously had and at no point did I restore my phones.
To prepared for it I made a note of all my apps.
Also I found that WiFi sense was a battery killer so turn it off.
