I've never used the bulk migrator...but there are a couple of things you might want to check.
- Can you manually create objects in this context without getting this error?
- Is the bulk migrator attempting to set objects to a state that doesn't existing in your lifecycle template?
- Is the OIR in use for this context pointing to the correct lifecycle template?
- Is is possible that you need to update the lifecycle template on your template parts (.prt, .asm, etc.)?
