NAME
    gcloud artifacts docker upgrade migrate - migrate projects from Container
        Registry to Artifact Registry

SYNOPSIS
    gcloud artifacts docker upgrade migrate [--copy-only]
        [--from-gcr=GCR_HOST/PROJECT_ID] [--last-uploaded-versions=N]
        [--max-threads=MAX_THREADS; default=8] [--projects=PROJECTS]
        [--recent-images=NUM_DAYS] [--skip-iam-update]
        [--to-pkg-dev=PROJECT_ID/REPOSITORY_ID] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    Migrate projects from Container Registry to Artifact Registry

EXAMPLES
    To migrate a project my-project using gcr.io repositories:

        $ gcloud artifacts docker upgrade migrate --projects=my-project

    To migrate several projects using gcr.io repositories:

        $ gcloud artifacts docker upgrade migrate \
           --projects=my-project1,my-project2,my-project3

    To migrate a project using pkg.dev repositories:

        $ gcloud artifacts docker upgrade migrate \
           --from-gcr=gcr.io/project1 --to-pkg-dev=project2/repo_name

FLAGS
     --copy-only
        Only perform image copying

     --from-gcr=GCR_HOST/PROJECT_ID
        Container Registry host + project to copy from. This flag is only used
        when migrating to pkg.dev repos. Example: gcr.io/my-project

     --last-uploaded-versions=N
        Only copy the N most recently uploaded versions of each image. More
        than N images may be copied if new images are uploaded during
        migration.

     --max-threads=MAX_THREADS; default=8
        Max number of images to copy simultaneously. Consider quota usage when
        increasing this

     --projects=PROJECTS
        Comma seperated list of Container Registry projects to migrate to
        Artifact Registry gcr.io repositories.

     --recent-images=NUM_DAYS
        Only copy images pulled or pushed in the last NUM_DAYS days. NUM_DAYS
        must be between 30 and 90 inclusive.

     --skip-iam-update
        Migrate without changing iam-policy. Users without Artifact Registry
        permissions will not have access to migrated images.

     --to-pkg-dev=PROJECT_ID/REPOSITORY_ID
        Artifact Registry pkg.dev project ID and repository ID to copy to.
        Example: my-project/my-repo

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.
