123NET Data Center Migration Checklist

Housing IT equipment has a cost. Generally, building, managing, and maintaining an onsite rack space will cost you between $1,000 and $1,500 per month on average. Cloud services could prove even more costly if misconfigured. 

A data center migration is the deploying and transferring of an existing data center environment to the operating environment of another data center. It is a thorough process of plans for migration of the existing data center to a different site or facility. The 123NET Data Center Migration Checklist takes you through crucial steps, which focuses on downtime and risk reduction, in the migration of your data center. 

Developing a Project Plan

On average, data center migrations take 1 to 2 months. To build a data center, it takes 18-24 months. 

  • Engage & Pinpoint All Functions & Stakeholders Within the Affected Organization 
  • Find a Migration Manager that Handles the Process, Communicates Developments & Ensures the Project’s Fruition 
  • Facilitate a Strategy, Focused on Timelines, Budgets & Success Benchmarks 
  • Receive Stakeholder Approvals 
  • Craft a Communications’ Procedure to Keep all Parties Progress-Focused 
  • Identify Roles & Duties Before, During & After the Undertaking 
  • Consider SLA & Other Contracts for Terms/Conditions, Including Early Termination 

Inventory Assets & Applications

Building a data center requires 5 to 10 pieces of different equipment. On average, there are up to 5 types of equipment that is required. 

  • Explore if Asset Inventory Requires Discovery Software, Manual Completion, or Both 
  • Utilize Equipment & Hardware Stock to Explore Ownership & What Must be Migrated 
  • Finish Taking Stock of Network Connectivity 
  • Finalize the Tabulation of All Hardware Applications Running 
  • Establish Any Undocumented Hardware & Applications 
  • Determine Categorized Cabling & Decommissioned Inventory 
  • Achieve Identifying Labeling Structure to Determine Necessary Equipment & Transfer Timeline 

Planning of New Infrastructure 

The average data center layout has a Power Usage Effectiveness (PUE) between 1.75 and 2.4. 

  • Consider the Site Layout to Decide Where Equipment Placement is Implemented 
  • Implement a Virtual Layout with Equipment Location & Connection Path to Outcomes 
  • Confirm the Design of the Network with the Engineering Team 
  • Determine Cable Lengths to All Power & Data Connections to Minimize Post-Migration Potential “Spaghetti Cabinet” 
  • Establish IT Deployment Power Capacity Alignment for Each Row & Rack

1: Before Migration 

2: Day of Migration 

3: Post Migration 

Put Together a Migration Plan that Establishes Roles, Contact Information & Timelines 

Establish Accessible Movement Plan 

Confirm Migration is Successful 

Direct Project to Mitigate Critical Application Resource Impact (if possible) 

Make Sure All Equipment is Delivered 

Guarantee Network Operations Center (NOC) Observes Systems Working Again 

Schedule Migration Service  
(if needed) 

Ensure the Assembly of All Personnel 

Determine Equipment is Physically Installed & Connected 

Familiarize Yourself with the Site Layout 

Record Migration Progress 

Dispose / Decommission Old Cabling & Equipment 

Build Instructions for Device Installation  

Plan Additional Migration Changes 


Ensure Site Access & Security Clearance for All Necessary Team Members 

Structure Data in One Location 


Build Plans & Detail New Configurations to Determine Functionality 



Craft a Contingency Disaster Recovery Plan 



Plant Hardware Before the Move 



Determine Initial IT Asset Works 



Do a Dry Migration Run
