In a recent post I advised against switching from one practice management system to another. That refers only to switching from one major product to another. On the other hand if you are using an older system upgrading now is a good idea. The following is from Lorne Lavine and as usual I agree with him.
If you are using a program that is not being supported, my advice is that you switch now. You will have difficulty getting technical assistance if a problem develops, and your software will not have updates, such as new CPT codes.
