Snowdrop has been contacting customers in order to work across each specific situation and plan to transition to the new Google Maps Platform.
As a Premium Plan customer, there are a few points you must know:
From November 1st, all Premium Plan customers are able to migrate to Google Maps Platform pricing plan once the contract expires.
Some customers have obtained one or more Bridge SKUs to be able to expand their contract date after November 1st so they can comply with Google Maps requirements for GMP migration. When the customer's support date ends, they can auto-migrate to GMP.
There's no need to make any code changes to migration - Client IDs or API keys - as this will be automatically done for you on move to the new billing. Client ID, API keys and project numbers will be automatically released to the GMP billing account.
Your partner will set up a billing account for your project(s).
Once the Premium Plan contract date expires, the project will be "unlocked", allowing the new billing account to be associated with the project within the Google Console. This step must be taken by the "billing account administrator" (the contract responsible for the GMP implementation in the organization).
Once the project is associated with the billing account, the transition to Google Maps Platform will be immediately effective.
Google recommends enabling billing on the new account within 7 days.
You can benefit from some volume discount pricing depending on your usage and API calls per month.
There are changes to the Terms of Services and these need to be understood on transition. Once again, your Reseller can take you through these as you require as well as ensuring compliance of your deployments.
