Bolt to Bolt+ HD Swap

I have a Tivo Bolt with a 4TB HD that I swapped in about a year ago. It is working fine with plenty of capacity. However, I've just ordered a Bolt+ for the 6 tuners but it only has 3TB and of course doesn't have my existing recordings.

Can I just swap my existing 4TB HD into the Bolt+? Will the new box have any issues recognizing the HD or will I need to do something special?

Thanks!
