How to migrate/upgrade Elastic Cloud v6.8.18 (Elasticsearch + Kibana) to 7.x version

Hi,

I'm new here. I'm looking for the (proper or best) way to upgrade/migrate AWS an Elastic Cloud v6.8.18 (Elasticsearch + Kibana) deployment to version 7.x.
I have found suggestions related to restoring a snapshot from the 'old' cluster to the new one, but apparently we cannot create a new deployment on the version we currently have to subsequently restore a snapshot.

Work with snapshots | Elasticsearch Service Documentation | Elastic.

What would be the in-place way?

I consider the following document https://www.elastic.co/guide/en/elasticsearch/reference/7.17/breaking-changes-7.0.html and additionally need to change the region for this new deployment updated to us-east-2.

Please do you have any additional suggestions or considerations for this scenario?

Thank you very much.
