I’ve done a couple cluster switches from k8s on AWS to other providers like Digital Ocean and GCP. As far as I recall we had no issues and one of those was done in about an hour were most of the time was spent waiting for pg_dump/restore. Note that most of these were not production clusters so switch-over was just data restore and DNS changes. I build clusters from the start to not use cloud-specifics where possible and all cloud-specific configuration is on the cluster edges in terraform which you have to rewrite anyway when switching clouds. Auth things like IAM permissions are not an issue if everything is “in cluster” and auth/permissions are checked there. Most of these deployments consist of several application servers, PG databases, redis, rabbitmq etc
