# Upgrading the Vault EKM Provider
~> **Note:** The upgrade process will put the database into maintenance mode and
require a restart. It is highly recommended to test this procedure in a
staging environment prior to running it on a production database.
1. Disable the Vault EKM Provider, and verify it is marked disabled:
```sql
ALTER CRYPTOGRAPHIC PROVIDER TransitVaultProvider DISABLE;
SELECT * FROM sys.cryptographic_providers;
```
1. Install the latest version from [releases.hashicorp.com][releases], following
the instructions in the installer.
1. If you get a "Files in Use" prompt while running the installer, select
"Do not close applications. A reboot will be required", and restart
after the installation has completed.
1. Reload the provider DLL:
```sql
ALTER CRYPTOGRAPHIC PROVIDER TransitVaultProvider
FROM FILE = 'C:\Program Files\HashiCorp\Transit Vault EKM Provider\TransitVaultEKM.dll';
```
1. Now re-enable the Vault EKM Provider and verify it is both marked enabled
and the version reported matches the version of the installer:
```sql
ALTER CRYPTOGRAPHIC PROVIDER TransitVaultProvider ENABLE;
SELECT * FROM sys.cryptographic_providers;
```
1. Finally, restart Microsoft SQL Server.
