Hi,
We are updating UAT environment from 10.0.10 (10.0.420.30016) to the latest version 10.0.12 (10.0.507.10035) but failed.
Error message in Log is "The field 'CustTrans_Voucher' on the extension 'CustAccountStatementExtTmp.TBMTDD53' already exists. This extension cannot be applied to the base element." where CustTrans_Voucher is a custom field created in table extension CustAccountStatementExtTmp.TBMTDD53.
I assume Microsoft is adding this CustTrans_Voucher new field in the update and the field name is conflicting with our custom field name, hence causing this error.
So I performed rollback but it failed with same error. From here, I can only resume the rollback and it will fail again and again.

At this point, what can I do to fix the environment?
Thank you.
