Balena VPN to Cloudlink Migration - Restart Question

I have a question regarding the migration from the vpn to the cloudlink enpoint described here:

If I understand the first remark correctly at the moment everything should work normally until the 10th December and for any device with v2.14.0 < balenaOS < v2.61.2 (e.g. balenaOS 2.45.1+rev4) a simple restart will be enough.

What’s unclear to me: Does this restart has to happen before 10th December or will a power cycling of the device after 10th December also work (I’m aware that a remote restart won’t be possible since there won’t be VPN connection)?
