big dig upgrading to official technic pack... lost multiplayer save?

[zorn]

My friend who runs the server I play on said that upgrading to the new 'official' big dig pack meant that we lost our world save. Is there any possibility that he made an error? He said only single player worlds could be moved over...?

Well Technic Pack was a Primarily Singleplayer pack. Technic Pack never supported MP.

But there are big dig servers posted here, did they all have to restart their worlds with this changeover?

well I played from Alfa and beta versions and I think that lots of time the single player worlds will get corrupted when doing a file trasfer

Thats what his hosting company told him, that the file was corrupted.
