WotLK Transferring characters from Frostmourne to Icecrown

[Supru2137]

Hello, I'm playing on frostmourne realm and I found out that Frostmourne is a seasonal realm and the character will be reset at the end of the season. I heard that I will be able to transfer my character from Frostmourne to Icecrown, but I don't know if it will be free or not and how it will work.

I will be grateful to the person who will explain to me how the character will transfer and whether it will be free.

It will be free and relatively painless
