Legacy File server Migration, reorganization and  working process optimization

Why? Because having a mess is expensive in different points of view.

  • Hard to administer and keep track of change management
  • High rate of file and folder duplicates
  • Disordered working processes
  • Miss-configured permissions and inheritance
  • Security gaps over the file server and Active directory users and groups
  • Audit and compliance logging amount of data in the SIEM systems triplicated
  • Megabytes costs money

The Solution?

  • Migration from Microsoft Windows Server 2012R2 to 2016
  • Active Directory reorganization
  • Working  processes optimization and documentation
  • Security measures
  • Separation of duties
  • AAA and CIA Awareness for the working team

We wish to share a quick post regarding a just finished migration and reorganization  and process optimization in a client environment.

The scenario

Having a legacy file server with more than 10 million of files, folders and a lot of shares with multiple NTFS permissions as an inherited legacy from the last 20 years of a hard working company is a project where you for sure will need serious planning, resource managing and high level of communication skills to receive the best information from your users.
The project was divided into phases as a project should be. The first phase is to collect information and folder ownership, usability, work processes.

The second is to create a new folder structure and start thinking about Active Directory group memberships in order to apply explicit and mandatory permissions to several levels of the folder structure.

Collaborating with your Human Resources department is crucial since the department workflows will become a policy to nest your Active Directory Security Groups in order to enhance your NTFS permissions to allow access to the data in a new and better manner.

Creating a backup of the source data server, synchronizing data to the target server with technologies like  Microsoft DFS and remember to apply best security practices to that new file server, hardening.  And keep your old data, the users might need some missing files after all.
We had achieved this goal with several security improvements, data de-duplication rates are big and the comparison of the old and new servers amount of used disk space results in a big amount of archived data which is not used by users in a yearly basis.
This is if you are planing a Process reorganization and optimization one good argument to achieve that or even to start thinking about that is to make an objective overview of how your data, files, folders and departments are collaborating, in many legacy systems to take a look into the file Server, will make you rethink your strategy.
