    Sorry you have to deal with this. You can stay on App Engine. Here is what to change before January 31, 2027:

1. Find apps on old runtimes. In the console, open App Engine and check the runtime of each service and version.
2. Choose a newer runtime. Pick a supported Python, Java, PHP or Go version. Plan time for code changes.
3. Deploy and test before the date. Move each service and test it before January 31, 2027.

    If you do nothing
    > What happens if I do nothing?

Google Cloud says:
- If you do nothing: Apps on a decommissioned runtime may be disabled without further notice.

You can stay on App Engine. To choose when it happens, make the change yourself before January 31, 2027.
