> # Database Merge Guidelines

> A database merge refers to a union of the configuration database and static (unlearned) entries in the active database.

> When merging the database between two fabrics, follow these guidelines:

> - Verify that the activation status and the auto-learning status is the same in both fabrics.
> - Verify that the combined number of configurations for each VSAN in both databases does not exceed 2 K.

> Caution | If you do not follow these two conditions, the merge will fail. The next distribution will forcefully synchronize the databases and the activation states in the fabric.
