What content are you moving to 2238? What errors are you getting? You'd need to provide more info, or else you can't get any help.
2238 and TLA (depending on revision also) is really quite different, they had several years of separate development, with 2238 we have a fair bit of "own solutions" and TLA has a lot of utility code that doesn't exist in 2238 so that may be the reason why you are getting errors, again if you provide errors we'd get more of a clue.
