Good Afternoon Ladybugg
I really wish I had some good news for you. But the truth of the matter is that once you upgrade your service say from regular phone to fios service, your services are routed differently, you are moved to a new telephone switch and new voicemail platform and old info is erased. This is one of the big downfall of having voicemail. If your company were to make a change or your voicemail box needs to get reset for what ever reason you stand a chance of loosing your messages.
I really wish I had some better news... It is not like they can move you back to old service and all you old messages will re appear.. once removed they are gone.
Sorry
