Well, I updated in this order, note that all changes I did, were in SSP (I've copied my world folder from server to saves folder in client folder):
1. I've made NEI Dump file include both Item, Unused and Block IDs. Then I've copied .txt dump file into mIDas Patch folder and renamed it to "Old NEI"
2. I've updated both client and server to 1.1.8 tekkitmain (I removed tekkitmain folder and updater made new one)
3. I've made new World in 1.1.8 with same seed, which had old world.
4. I've made new world NEI Dump. Then I've copied .txt dump file into mIDas Patch folder and renamed it to "New NEI"
5. I've made patch file, then I've applied that patch to the old world in mIDas GOLD
6. I've exported my stuff with MC Edit from old world
6. I've imported my stuff with MC Edit to new world
After that I just start play in my updated world with out any problems. I can confirm only one client crash, but but I just need to slow down, when I pass that location.
Sorry for my english, I hope this wall of text was useful.
