Reclassifying multiple GL offset in Accounts payable to single GL offset

Hi,

Presently in our Accounts payable  we have different GL offset for each trading partner but  pointing to same object accounts which has open  balances . Below is an example:

   

Company	GL offset	Object Account	Amt
26600	4820	482010	1000
26600	2001	482010	2000
26600	2002	482010	8000
26600	2006	482010	9000

We want to keep just one GL offset account instead of multiple GL offset account.

What is the best approach to move the Balances from Multiple GL offset account to one GL offset account without any integrity issues between AP and GL ?

Thanks,

Prakash
