Accommodating Legacy Values in Revision Labels
All values that have been set in a revision label for any object that can be revised should remain in your scheme.
To allow values in revision labels on existing objects, but exclude the values when creating new revision labels, add the following attribute to the value tag that defines each value you want to exclude:
legacy=”true”
For example, to exclude the P2 value shown in Format of State-based Versioning XML File, use the following:
<?xml version="1.0" encoding="UTF-8"?>
<scheme>
<series name = "name1">
<seed name = "seed_name1">
<value>P1</value>
<value legacy="true">P2</value>
<value>P3</value>
</seed>
</series>
</scheme>
