Renaming the default branch (master) to a different name.

rename_the_master_branch_in_git

# consider the default branch is master and we want to rename it to prod

# Steps to rename the default branch master,

# 1. Branch off from master to a new branch called prod.
git checkout -b prod

# 2. set up upstream and push the renamed branch
git push -u origin prod

# 3. Update the default branch as prod in bitbucket, Github, gitlab, etc.
# Incase of bitbucket, 
# go to [your repository] >> Repository Settings >> General >> Repository details >> Advanced >> set Main branch to prod

# 4. Delete the master branch from your local
git branch -d master

# 5. If the master is a restricted branch, then either disable the permission or edit the permission to make the prod as restricted.

# 6. Now delete the remote master branch
git push origin --delete master

# 7. Update the upstream's remote HEAD
git remote set-head origin -a

# To accommodate the changes for the other team members, do the following steps,

# 1. Fetch all the new branches
git fetch --all

# 2. Update the upstream's remote HEAD
git remote set-head origin -a

# 3. Set upstream to prod
git branch --set-upstream-to origin/prod

# 4. Rename master to prod
git branch -m master prod
