Will improved scan/import features with new versions apply retroactively?

Hi,

I'm in the middle of getting LB set up for a new system. I just recently finished the build, but before I even had the parts I started importing my collection on a different machine (that I'm going to essentially just copy over with the same file structure) so I could get ahead a bit. 

LB's scanning features are obviously always being improved. For example, I see that in 10.11 this change was noted:

Improvement: No-Intro ROMs with multiple titles (separated by the ~ character) will now use the first title as the game title for better scraping

I started importing my ROMs/games in I believe 10.8 and have already imported most systems that I have a No-Intro set for. If I copy my install over to the new machine and select the option for re-scan/check for added content, will the new "rules" be applied and will the scrapped data be modified for the ROMs that are already in my collection? Or would I essentially have to start over to get the benefit of this and other related new features?

I want to end up with the most well organized collection I can, but if I have to re-import everything it will take forever and I'm afraid I'll forget some of the lest obvious tweaks I applied in very specific cases.

Thanks.
