Tekkit server upgrading

[hatchcatch020]

Hello, I have been running a Tekkit server on my local machine for some time now. I was running the 1.2.8e version of Tekkit and therefore was using a server to compliment that. I decided it was best we update to a more stable version so I therefore updated my client and then downloaded the latest server files. I thought it was going to be as simple as replacing the generated world file with our old world file and things like server.properties. I did this and however got errors which I assume are regarding IDs of items and blocks already being used by other mods. I was wondering if I have missed something out when transferring from the previous version to the latest version. I will attach the read out from my server. 

I'm sorry if this is the wrong place to post this but I could not find a more relevant place.
