How to Guarantee a Completely Secure Migration to M365

Many organizations are now choosing to migrate to Microsoft 365 for a number of reasons including collaborative working options and Microsoft 365. Doing so has a number of advantages, but the movement of data can be difficult. A main consideration during the migration process can be maintaining data integrity whilst securing the data throughout the migration. Here are some migration security measures to consider to ensure a secure migration to Microsoft 365.

Encryption of Data

End-to-end encryption is the most secure way to communicate securely and with privacy online. The messages are encrypted at both ends of the conversation which prevents anybody in the middle from reading the private communications. Neither hackers nor unwanted third parties can access the encrypted data on the server.

CloudM Migrate has end-to-end encryption between migration endpoints. The option to Self Host CloudM Migrate will completely isolate your migration data from your source environment to the destination cloud tenant.

Both primary and secondary servers use the following components to temporarily store migration data during a migration.

  • Encrypted SQLite databases (AES256)
  • Encrypted temporary file storage (AES256)

Where CloudM Migrate requires a username or password to interact with a system, and stores sensitive data like this, that data is stored encrypted within SQL Server (AES256). SQL Server 2019 Express is installed by default but you can specify your own SQL instance.

Know your source data

Before you start migrating data, you need to know exactly what it is you’re moving. Ensure you know the format of the data, where it is in the system, and if it does actually need to be migrated. Ensure the data is clean and any data that does not need to be kept, can be disposed of to reduce costs and decrease the chance of security risks.

Know your destination

Knowing everything about where the data is coming from is half the battle, the other half is knowing where it’s going.

Ensure that you know the exact destination your data will be going to. From simple things like username conflicts to license fees, the new system will have its own set of rules and regulations.

For example, if you are moving from a legacy endpoint to Microsoft 365, you need to know that all data will be working as expected and the appropriate security compliances are in place. It is also important to ensure everything will be compatible

Back up data

Before the migration begins, ensure all data has been backed up, especially the files you will be migrating. If there are any issues or problems during the migration, such as corrupt or missing files, then you can always restore from the backup.
