Hello. I try to migrate client from 8.1 to 8.5 and I have a problem.

In 8.1 VARVc was redifinited and in main key added additional index.

But if I try run 8.5 with this datadef hal.log tels me next:
"Error 1:redefinition of register VARVc is not allowed, please use RecordAddBegin()/EndRecordAdd()"

How can I solve this case?

Before

MainKeyBegin(Code,0);
KeySegment(Code);

After
MainKeyBegin(Code,0);
KeySegment(Code);
KeySegment(VARGCode);
