Impact of upgrading SQL Server 2008 R2 edition on existing web applications
Posted on 2014-11-12
We are looking to upgrade the edition of SQL Server 2008 R2 that is installed on one of our production web servers that we maintain. We need to upgrade the edition from Standard to Enterprise.
The reason for the upgrade is the need to use features like Audit logging, TDE, etc.
Before we upgrade, what precautions are recommended to be taken (besides taking a backup of the databases) ?
Since there are applications hosted on the server that use SQL server (we don't have access to the code for all the hosted applications), how to find out if there will be any impact on these applications once the upgrade is done ?
Besides the downtime (which i assume will be there during the upgrade), is there any other thing to be taken into consideration (Server logins, etc.) ?
