SWADE Compatibility w/ modules

Hello, I am very new to Fantasy Grounds, in fact it has been a couple of years since I have been on this site. As a fan of Savage Worlds, I have a question about purchasing the proper core rulebook. If I purchase SWADE, and purchase an older game, like Hellfrost, will they be compatible? Will HellFrost run on the new ruleset? If this question has been asked before, please point me to the answer. Thanks in advance for your help.

Yes, if a link to a non-existing edge/skill (in SWADE) is in the module you may get an error but otherwise it works.

Doswelk, thank you for your response, I appreciate it.
