Incorrect transactions in Bank account

I have several operating units setup each with one or more than one bank account. Example.

Operating unit 1xx has a bank account xx-111-222.

Operating unit 2yy has a ban account yy-333-444.

Some transactions that were imported from receipting system (bespoke) thru AR module ended up in account xx-111-222 instead of yy-333-444 coz the transactions originated from unit 2yy. This was caused by a fault in the AR setup. The fault has been rectified, but we want to transfer the incorrect transactions to yy-333-444 from xx-111-222 in order to accomplish bank rencocilliation duties. The fault in the AR setup caused transactions from other operating units (34) to be posted in xx-111-222 account. The remedy provided if any would require to solve for other operating units as well.
