I was digging my notes and found this one, I prepared it long back when 'NW2004s BI 7'was making an entry...but this is still so much relevant for any upgrade / migration road-map. So thought of sharing...
Defining “Concept of Migration” will pass through the following stages –
Analyze - Identify - Assess - Decide - Define
1. Stage I Analyze:
- Analyze – Purpose of this stage it to analyze the existing solution.
- Deliverable – Document covering existing analytics, features functionalities etc. which may be considered for migration or for implementation post migration.
2. Stage II Identify:
- Identify - The aim of this task is to gather and prepare any information available about additional functions etc. in the newer version.
- Deliverable – Overview of additional content, functions etc. in the newer version.
3. Stage III Assess:
- Assess – Impact Assessment of new and modified functions in the newer version, taking into account of the solution currently being used (input from stage I) and new functions available in newer version (input from stage II). Do initial impact analysis.
- Deliverable – Assessment Document, a basis document for compiling a plan for documentation and training.
4. Stage IV Decide:
- Decide - The aim of this task is to justify the necessity migration / upgrade.
- Deliverable - An overview document of the various technical and functional factors affecting the upgrade / migrate decision.
5. Stage V Define:
- Define - Define the optimal target features, functionalities for migration / post upgrade implementation and then freeze on scope & plan.
- Deliverable – “Concept of Migration” (Migration Roadmap) covering frozen plan and scope of migration / implementation of new features & functionalities.
