You can now transfer Wyndham points to Total Rewards RCs, or vice-versa -- up to 30k points total (in either direction).
These points transfer at a 1:1 rate (that's what I heard, but it's not verified).
Wyndham points, however, tend to be worth less than a penny each. Here's an analysis: https://www.valuepenguin.com/wyndham-rewards-program
So it's probably better to transfer Wyndham points to RCs, rather than the reverse.
You can only do it in multiples of 10,000 points.
