According to Blizzard

"In the midst of fulfilling the request that we've received from WOTLK Gold players for a long time and we're expecting there to be many new Classic players joining new players for the first-time in Wrath of the Lich King, and some of them might be worried about how they'll be feeling left out," Blizzard's forum post says. "Fresh start realms should give those players the opportunity to feel on the same level like everyone else."

There are certain rules for creating the character on a new start server. At least for one month, gamers won't be able to benefit from an upgrade for their character that is paid or fresh start servers won't be able to transfer players on other servers in the same length of time. Anyone who wants to play an online Death Knight in Wrath of the Lich King Classic will need to hit level 55 on a character that is on new start servers before creating an actual Death Knight character on that same server. It won't be an issue for other servers, including Wrath of the Lich King servers, as players will be able to make one Death Knight on any server without needing a level 55 character.

According to Blizzard according to Blizzard, according to Blizzard, the Wrath of the Lich King pre-patch should last from two up to six weeks. This means those who join fresh servers will not have a lot of time to hit max level before they are able to go to the brand fresh continent Northrend. When the pre-patch is ready, all existing Burning Crusade cheap WOW WOTLK Classic Gold Classic servers will automatically be converted to Wrath of the Lich King Classic servers.
