Protection type is not initialized
When upgrading to SES 6.2.SR1, the following prompt appears:

Cause
This means that the Protection Type for 1 or more users in the database is set to NULL.
To confirm, if we open up the SES database in SQL Management Studio and run the following query;
select *
from dbo.tblDBKs
where ProtectionType is NULL;
Resolution
Method one:
-Click on YES and it will initialize all these users to use Password Protection as default.
Method two:
-Click on Cancel
-We can manually set the protection type for these users with the following values:
0 = Password protection
1 = Token protection
-Rerun the upgrade again and the prompt should not appear anymore.
