It's important to have a frame that dimensionally will hold a disc wheel hub and you have a method to attach calipers to. Also, skewers and open dropouts are now frowned upon for use with disc brakes in favor of thru-axles. Anything else is up to how well you DIY and are willing to put up with the potential risks.
