Snapping to whole frames

Hello folks,
I could use a little advice:
I spent the last week creating an animated title sequence purely in AE at a standard 29.97fps and then right as I was finishing, the client told me that it was going to be shown in the UK and needed to be 25fps.
I know... I should have asked before starting. Seems like I never learn.

As there was no actual footage in the sequence I didn't think it would be a big deal to convert the project from 29.97 down to 25 - but now all of my text layers are not snapping to whole frames. They seem to lie half-way between frames. To fix this I'm having to go in and manually adjust every single layer... and there are a LOT of layers.

Does anyone know if there is a better way of doing this?
Was there something I should have done when converting - other than just going into the project settings and changing the frame rate?

Thanks in advance!
