moving from new to old?

I'm not sure if anyone has asked this question is it passable to move a character from a new world to a old one? Cause i was thinking of making my pirate character in the new world and later on move him back to the world i normally play?i know that the limits on the char world item limits a character from moving from old world to new one but does the same apply to a char made in the new world moving to a old?
