Impacts when i update from 2.14.5 to 3.10?

Hi
Soon I will need to upgrade from 2.14.5 to version 3.10.
Can you tell me if I can expect to get big problems when updating or if it is supposed to go very smooth?
I have made a lot of translation in language files, and it is not translated directly to danish, because I use the EB a littlebit unusual.

Will there be any other problems when updating do you think?
Is there a special update package for this update? Is it a special price?

Thanks for your answer
