az --version
az extension add --name azure-devops

• Configure git to avoid issues

git config --global pager.tag false

• Connect to Azure (ref. Sign in with a personal access token)

az login
# or
export AZURE_DEVOPS_EXT_PAT=xxxxxxxxxx

• Run the migration script (ref. az repos)

scripts/migrate_azure_repos.sh <oldorg> <oldproject> <oldrepo> <neworg> <newproject> <newrepo> <repoid> <tempdirpath>

• Optionnally, migrate all repositories of a project

while read repository
do
  name=$(echo "$repository" | jq -r .name)
  id=$(echo "$repository" | jq -r .id)
  echo "Repository ${id}, ${name}"
  scripts/migrate_azure_repos.sh <oldorg> <oldproject> $name <neworg> <newproject> <someprefix>$name $id <tempdirpath>
done < <(echo `az repos list --organization https://dev.azure.com/<oldorg> --project <oldproject>` | jq -c '.[]')
