Hello, if you want to migrate to new prometheus instance in Ubuntu, just point the write-url to prometheus/api/v1/write and keep the max-read-duration low, maybe 1 minute. This is because I recall that when I was testing migrating to Prometheus, anything larger than 1 minute block makes Prometheus error out, because Prometheus wasn't meant to be written into.

However, if you want to migrate data to Promscale, then you don't need any limit on max-read-duration.

BTW, can you share why you are using prometheus-postgres-adapter. The project is no longer maintained and instead, we recommend to use Promscale.
