I checked the EQ website and I don't see any way to upgrade from EQ5. They also don't have upgrades to EQ7 anymore, because EQ8 is the current version. If you buy EQ8, I have no idea if all of your files from EQ5 are compatible. You might want to call or email them to find out what your options are. Here is a link to the website:
