Ready, Set, Migrate
Our unique, 3-phased approach to Windows Server 2003 migration gives you a comprehensive sense of what your data center looks like, what solution makes the most sense for your situation and how the migration will be implemented.
In the second phase of our approach — actual migration — our services include a premigration checklist, upgrading hardware where necessary, upgrading to Windows Server 2008 R2 or 2012 R2, and a post-migration checklist.
At pre-migration, our focus is on the validation of the planning and discovery phase. Trent Viavattene, senior manager of the core infrastructure practice at Insight, expands, “You need to know who you’re going to contact in regard to the applications, who’s going to validate the app after the fact, how user communication will be handled and who’s going to collect all the information about the server.”
You should also have a methodology planned in advance for the server’s migration. Verify that you have all the information required and the proper change approvals have been finalized.
“Then, you’re ready for migration,” says Viavattene. “By that time, you’ve identified that the application is compatible, and you’ll fully understand the known state of the new server.”
“We help our customers map the servers that are going to be moved to the change window that best corresponds with the most minimal usage of that application,” says David Mayer, practice director of Microsoft® solutions at Insight.
Most organizations with well-oiled IT practices have designated change windows. “If we’re migrating email, we would help the customer perform some testing to understand the usage level to determine when that specific workload is at its minimum usage,” explains Mayer.
After the migration is complete, Insight ensures there aren’t any errors on the new server and that we can establish connectivity to the new server. “Once all of the server components have been validated, application teams perform their validation at the application level,” states Viavattene.
“Outside of the application owners, we establish a group of super users to ‘kick the tires.’ They make sure that everything is functioning as expected and that all data are accessible,” he adds. Once validation is complete, the general user base can begin using the new server.”
