Migrating to new cluster hardware

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :Sql Server


We're moving to a new blade server cluster from dell cluster and are doing a rebuild of the OS and SQL server - then we'll do a SAN disk move and get everything running on the new machines.  The OS is being rebuilt on windows 2008, moving from 2003.  We have 3 instances on the old server, so we will install 3 clustered instances using the same instance names - but with different sql virtual names, since they will need to coexist on the same domain while we do this.  So  oldserver\dev01 -> newserver\dev01 - and then we need to forward the old virtual names and a VIP to the new virtual sql names.

We'll get everything set up on the new cluster - MSDTC, Reporting Services and the Instances.  Then we'll disconnect the san drives and reconnect them to the new servers using the same drive letters.   The new servers will also take over the old servers IPs.  We'll have to monkey with the new server's Cluster SQL IP resource and the DNS entry for the SQL Network Name to bring SQL up.

We'll then add disk dependencies to the clustered sql groups and do a restore of the master and msdb databases.  Then we'll update DNS to point our old F5 VIP to the virtual sql names - (VIRSQL\instance) and or old sql virtual names to the new virtual names.  I'm thinking we may need to update the system tables afte

Can we put SQL Cluster on Different Hardware type


Hi All,

We have purchased HP DL580 G5 Server with Intel 74XX Series Processors and DDR II RAM 4-5 months back.

We are now going to purchase new node for Cluster, which will be HP/IBM Intel 75XX Series Processor and DDR III RAM.

We are going to put SQL Server 2008 R2 64 Bit with Windows Server 2008 R2 64 Bit Enterprise Edition.

Is this configuration is supported by the server Cluster?

Kindly give us the guidance?


SharePoint document migration challenges when migrating files and folders

There are several challenges when migrating documents to Microsoft SharePoint. While these challenges can be overcome, they are a real pain if the migration source, content and file systems are not SharePoint friendly.

PollLockedSessionCallback error after migrating to 2.0

Migrating ASP to ASPX.... where to set 301 redirects


Hello, I'm updating around 15 pages from .asp to .aspx (.net 2.0)

My question is, do I have to put a header redirect 301 (permanent redirect) on each old file, or can I put it in global.asax file with a case checking for any of the 15 files?

I some tries to go to old.asp will it execute global.asax anyway?

What would the best aproach be?

Data Points: Migrating from ADO to ADO.NET, Part 2


As you move forward with your use of ADO. NET, you'll need to know how to approach situations that you previously learned to handle in ADO and now have to tackle with ADO. NET. Just as n-tiered solutions developed using Visual Basic®, C++, and ASP often rely on ADO for their data access needs, Windows® Forms, Web Forms, and Web services rely on ADO.

Pocket PC: Migrating a GPS App from the Desktop to eMbedded Visual Basic 3.0


A Global Positioning System (GPS) device captures lots of interesting information that can be used in many ways. This article presents a custom application built with Visual Basic that collects data from a GPS satellite and charts the course of a user relative to the satellite. Such an application is obviously well suited for use on a handheld PC and porting the original application to eMbedded Visual Basic for Windows CE is described. The differences between Visual Basic and eMbedded Visual Basic, such as support for specific control and data types, are explained. Tips for dealing with reduced screen real estate on a handheld PC, debugging, and running in an emulator are also discussed.

Migrating aspnet tables to dev server - having issues



We're trying to migrate a one of our apps to our dev server for testing and development, but we're having problems with the membership functionality. We can add users, but there seems to be a disconnect with roles. We can query the aspnet_users table and find the new user in there, but when we query the aspnet_usersinroles table, that user id is not present.

We're also unable to run the Roles.GetUsersInRole("somerole") method. It returns 0 records. When I run Roles.ApplicationName, it returns the correct name, so .NET should be passing the correct app name.

We're just a little baffled. If anyone could shed some light on what could be the issue, we would appreciate it.

Thanks! :)
