Can I activate the DC portion of my pension before the DB portion of my pension?

I have a deferred DB pension. I also have a DC pension linked to the DB pension with the same employer. I made a lump sum contribution when leaving my old company.

My DB pension will kick in in a year or two.

In the meantime can I activate the DC portion of my pension or do I have to wait until the DB starts?

No. You must activate pensions from the same employer at the same time.
