Server Upgrade

What is the easiest way to upgrade an existing 1.0.13 world to 1.1.4? I tried to move the world files into the upgraded server and get the following error message:

2013-04-17 10:46:16 [sEVERE] [ForgeModLoader] A TileEntity type universalelectri

city.prefab.multiblock.TileEntityMulti has throw an exception trying to write st

Is there a way to clear this up? Will there be any issues with the upgraded world? Also this is a test world used from a backup of the original so if its hosed and I am stuck on the older version its not a big deal.
