    "post_text": "We run a GitLab 19.3 using an Omnibus installation on a single VM. Our container registry runs separately, in a docker container using the GitLab provided registry image. Registry data is stored on NFS, and metadata currently uses the legacy filesystem based storage. The registry holds about 6 TB of data.\n\nWe’re planning a migration to the registry database and would appreciate any advice on the architecture. My understanding is that GitLab already has a separate logical DB for registry metadata in its bundled postgres instance. Could our separate registry node use that DB?\n\nIf so, we would need to enable TCP access to Postgres on the gitlab VM and restrict access only to the registry VM. Is that a recommended and secure setup?\n\nWe’re especially interested in how others have handled the migration at this scale, including downtime, security and ongoing maintenance. Thanks for any guidance or experience you can share",
