  1. All hotfix packages are cumulative, the latest one will include all the fixes in the previous ones.
  2. Conduct basic testing before rolling out hotfixes to production systems.
  3. Deploy hotfixes to only the affected production systems. (For CBS AUA Hotfix, disabling AUA for each user before updating would be a good practice.)
