I found the following link in the Workspace help pages:

https://support.google.com/a/answer/60217#nonbiz&zippy=%2Cwhat-if-i-use-g-suite-legacy-free-edition-for-personal-use-and-dont-want-to-upgrade-to-a-google-workspace-subscription

> What if I use G Suite legacy free edition for personal use and don't want to upgrade to a Google Workspace subscription?

> Upgrading to a Google Workspace subscription is a seamless transition for all customers currently on the G Suite legacy free edition.

> However, we understand some customers may not use their G Suite legacy free edition for business and may be interested in other options.

> If you have 10 or fewer users in your group and do not use your G Suite legacy free edition for business, please sign in to your administrator account to provide more information.

> <Sign in to an administrator account (doesn't end in gmail.com)>

> Note that even if you decide you don't want to upgrade to Google Workspace, you'll still retain access to additional Google services and paid content purchased though non-Google Workspace services made with your legacy edition account (such as movies purchased on Google Play). Learn more above.

The <sign-in> link turns into a google form when logged in. I was able to fill it in and specify that I'm only interested in personal use.

From the same page - it also seems like they'll provide a way to migrate to a non-Workspace account:

> If I don’t want to upgrade to a paid subscription, can I transfer my data?

> In the coming months, we'll provide an option for you to move your non-Google Workspace paid content and most of your data to a no-cost option. This new option won't include premium features like custom email or multi-account management.

> You'll be able to evaluate this option prior to July 1, 2022 and prior to account suspension. We'll update this article with details in the coming months.
