Description

I am doing performing repository migrations for a customer from Bitbucket server to GHEC-EMU using GEI bbs2gh tool.
For certain repositories, the default branch from the source repo is not correctly retained in the target repo.

For instance:

• Source Repo in bitbucket server has develop branch as default branch
• Migrate this repo using GEI bbs2gh tool
• After migration, the target repo in GHEC has the master branch as default

Reproduction Steps

Migrate source repo in bitbucket to GHEC using the below cli command

gh bbs2gh migrate-repo --aws-bucket-name "{aws-bucket}" --bbs-server-url "{server-url}" --bbs-project "{bbs-project}" --bbs-repo "{bbs-repo}" --github-org "{github-org}" --github-repo "{github-repo}" --target-repo-visibility internal

After migration, check the default branch on Github and it does not match with the default branch on the Bitbucket server.

This is causing an issue in a 100% validation of the pre and post migration of the repositories that the customer is aiming for.
