Migrating to a Dell PowerEdge R515 server from two legacy database servers

RAM, and has been optimized to reduce both power consumption

and heat dissipation.

WE SHOW YOU HOW: PREPARING FOR THE MOVE

Our accompanying performance and TCO/ROI reports show from

performance and cost perspectives why you should consolidate your

older database servers to a single Dell PowerEdge R515 and use

Hyper-V virtualization technologies with the added benefits of a

newer SQL Server 2008 R2 release. In this Guide, we address the next

question: How to accomplish this? We discuss planning issues, setting

up the Dell PowerEdge R515, the actual migration using a simple

backup/restore method, and post-migration considerations.

Evaluating your databases

As with any migration or consolidation, planning is a key element.

This is especially true when moving to a virtualized environment. You

must be aware of many specific details related to each physical server

you target for consolidation, including the maintenance window in

which you will migrate the server to its new environment, the users

the move will affect, and the configuration tasks necessary to

assimilate the databases into your consolidated environment. A more

comprehensive example survey appears in Appendix A. Information

to gather before consolidation includes the following:

 Server OS version and patch level

 SQL Server version and patch level

 Number of logins on this SQL Server instance, and what type

of logins these are (Windows or SQL)

 Current backup strategy and schedule for the databases on

this server

 Replication details for this SQL instance, if any

 Detailed information regarding permissions and roles

 SQL Server Agent jobs on this SQL Server
