How to mitigate the performance risk in data center migrations
We see more IT departments considering NPM/APM adoption when dealing with data center moves, mergers and consolidations.
Before the migration
1. Measure the end user performance in the initial situation
2. Collect the performance data to figure out how you migrate your systems
- Establish a list of all the critical application chains
- Dependency mapping: understand the dependency between the different hosts (infrastructure services like DNS, Storage, authentication servers, and all the hosts of the different tiers of each application, identifying which IP addressing may also be hard coded)
- Understand the network requirements between all these hosts (volume and bandwidth) and the performance profile of each type of communication (respective impact of network, server processing and data transfers on the end user response times)
3. Anticipate the added latency during the migration and the impact on the end user experience
Execute the migration
4. Keep performance under control during the move / migration
- any performance degradations resulting in business losses (productivity and / or revenue)
- any delay in the execution of the migration
- any lack of shared performance data driving to a lack of collaboration (between IT departments - network, system, database, applications) when troubleshooting slowdown issues
- finally any negative feedback on your team’s work
After THE MIGRATION
5. Analyze and identify remaining errors / misconfigurations
6. Measure and report on the end-to-end user performance after the migration
Once the migration is considered completed, you should measure the end user performance and report the variation (if possible improvement) which comes with the implementation of the new infrastructure.

Conducting data center moves / mergers / consolidation without a performance monitoring solution is a high risk!
- Provide you with a visibility on all applications and services in your datacenter (wide-angle view)
- Be able to capture the flows of all the application tiers (including the data exchanges inside the virtualization infrastructure or the private cloud)
- Provide an end-to-end performance visibility (from the network layers to the application transactions) to be used by all teams during the migration.
