Old White Labs Wit Yeast Question

I have some White Labs witbier yeast. It's at least 6 months old, probably more like 9-12. It's from a previous batch that I just scooped out of the trub after primary fermentation. It's been in my fridge the whole time.

I made a starter and it is doing well.

My question is: Is this still okay to use? It's been kept cold the whole time, and it was fresh from the first batch. And like I said, the starter is doing very well right now.

Go for it! It ought to be fine.

Coincidence huh, https://www.homebrewtalk.com/f13/testing-limits-yeast-viability-126707/

Every time I've used that wit yeast, it blows off like crazy, so if nothing else, you'll know pretty well that it's going.

The starter was absolutely a success.

I made another, slightly larger starter and dumped the first starter into it. It's now going well too. Stepping it up for a beer I'm brewing next week.

I'm going to start saving portions of every yeast I use if it's this easy to get it going after nearly a year in the fridge.
