Dear All,

One of my client having a requirement that he want to change Main account type and Main account category for all exiting accounts.

 As mentioned below screen:-

What is the best way to change and changing these details will cause for any issue. 

By importing all the details to the table "MainAccountCategory" and mapping to main accounts through code will achieve the requirement?  or  will it cause for any issue for old data and any other levels?. 

Any suggestion would be appreciated.
