Magic World still 1.4.5, can I manually fix this to 1.4.6

[Spodean]

I created a server for me and my friends using magic world.

We missed all the holiday stuff

Been using alot of the thaumcraft stuff, I have golems running all over the place, I've been working on creating silvertree nodes etc..

Azanor released a new version of Thaumcraft with more research, need to find fragments etc...
Because of these new fragments ive been restricting my adventuring because I want these new items and I dont want to make my world any bigger till the new chunks and biomes can be created using the latest Thaumcraft.

Not meaning to sound impatient, just want to know if I could at the very least update Thaumcraft to 3.0.1c or will the item id's end up jacked up, because I know there are a few more items that have been added.

Has anyone else tried to manually update this modpack?

Think Ill give it a go with a new world, just paranoid because I don't want to destroy my current.

I'm really new to this mod stuff, been playing vanilla for a long time and finally decided to give it a try when I saw FTB in one of Etho's videos on youtube.

I update it using Mindcrack modpack as base. Comparison show that most mods from magic world listed in mindcrack pack - so you can get mindcrack with disabled not need mods and manually update only missing mods (or get its from dw20 pack in fact). I not remember any block ids differnecnes problems in configs for mods in pack.
