If you buy this Reinstatement,
do not register the Reinstatement Code with Avid until you are ready to use it, because your new Plan will start immediately (upon registering the Code with Avid).
If you want to stay on (say) Pro Tools 12.5HD for a while, just hold on to the Code until you’re ready to upgrade.

Q: If I purchase a reinstatement and do not immediately redeem, will it expire?
A: No. When you purchase a reinstatement from a reseller the code does not expire and you are able to use it at a future time. (Important to note that the clock on your Software Updates and Support Plan starts when you redeem the code in my.avid.com/products/redemption.) Avid will continue to honor reinstatement redemptions after we discontinue selling them.
