What you need to do is to open the Master Key with the password it was created with on the other system and then close the key again. &nbsp;This will allow the new server to encrypt the master key with the Service Master Key and you will be good to go. &nbsp;You should not drop the key.

Thanks I'll try that next time.. I was out of time and so I did drop and create a new key. I was lucky enough to have the column stored elsewhere and a column to join on so nothing was lost. Thanks for your response,<br />

Dear Experts,<br />
<br />
I have a problem. We had a database promoted from dev to test via redirected restore.<br />
<br />
The database has an encrypted column. As you can imagine, the key no longer works.<br />
<br />
Is there a way to drop the key and recreate a new one? <br />
<br />
Or<br />
<br />
Do I have to drop the key, create a new key, then update the column with the values using the encrypt function?<br />
<br />
Thanks!<br />
