Without knowing how your split and servers are setup, I'll make some
(possibly bad) guesses.

If your secondary select method is currently set to nnmh like:
(setq gnus-secondary-select-methods '((nnmh "")))

You'll need to change that to:
(setq gnus-secondary-select-methods '((nnml "")))
Then restart gnus or re-evaluate ~/.gnus

I believe splitting only goes to the default servers

Now depending on how your split rules are setup, you should be able to
create nndir groups of each of your nnmh groups in turn (since nndir
is read only, your nnmh group should stay safe in case something goes
wrong)

When an nndir group is created then `M P a' in summary buffer and run 
`B r' to respool each message to what will now be nnml groups.

When this is done press `F' in group buffer to see all the new nnml
groups your split created.

If this is successful you can then do C-u G del on the nnmh groups in turn.
