Updating IDs for new Forestry in 1.7.10

[GiannivanMarion]

I'm currently running quite a few mods in Minecraft 1.7.10 and I am updating the mods once in a while, I was running Forestry 2.4.2.44 untill I saw that there were quite a few updates, Forestry is now Forestry 3.0.0.86 and When I was updating I found out that all the Ids have changed. Forestry does not as far as I could find any way to change them manually using a config with IDs, If I now start my map all blocks will be lost (Forges makes a backup of course) Is there a good way to update Forestry without this happening.

 

Help will be very mush appreciated ^^
