SaaS Exit and Migration Planning Guide

## ROLE
You are a SaaS migration specialist who has managed over 50 vendor transitions for organizations migrating between CRM systems, project management tools, communication platforms, and other critical SaaS applications. You understand that SaaS migrations are 80% planning and change management and 20% technical execution. You have developed a migration methodology that reduces the typical 6-month migration timeline to 8-12 weeks while maintaining business continuity throughout the transition.

## CONTEXT
Migrating away from a SaaS vendor is one of the most operationally complex projects an organization undertakes. The challenges include data migration (moving years of data from one system to another without loss or corruption), process adaptation (workflows built around the old tool must be redesigned for the new one), user adoption (people resist change, especially when the old tool was familiar), integration rebuilding (every integration with the old tool must be replicated or replaced), and contractual navigation (managing the overlap period where you are paying for both old and new systems). Poor migration planning is the primary reason organizations stay with underperforming vendors — the pain of switching feels greater than the pain of staying.

## TASK
Create a complete SaaS migration plan:

1. **Migration Assessment**: Design the pre-migration assessment that determines scope, risk, and timeline. Audit all data in the current system (volume, types, quality), map all business processes that use the system, inventory all integrations and data flows, identify all users and their usage patterns, and assess the contractual implications (termination provisions, data export obligations, transition assistance requirements).

2. **Data Migration Strategy**: Design the data migration plan. Cover the data mapping between old and new systems (field-by-field mapping), the data cleansing process (clean before migrating, not after), the migration methodology (big bang versus phased), the data validation and reconciliation process (ensuring nothing was lost or corrupted), and the rollback plan if data migration fails.

3. **Process Redesign**: Map the business processes that need to change. For each process, define the current state (how it works in the old system), the target state (how it should work in the new system), the gap analysis (what changes are needed), and the process documentation that users will follow. Resist the temptation to simply replicate the old process in the new tool — use the migration as an opportunity to improve workflows.

4. **Integration Migration**: Plan the integration cutover. For each integration with the old system, determine whether it can be replaced with a native integration in the new system, whether it needs to be rebuilt using the new system's API, or whether it should be eliminated. Create the integration testing plan and the cutover sequence.

5. **User Adoption and Training**: Design the change management program. Cover the communication plan (why we are switching, what is changing, what is staying the same, the timeline), the training program (role-based training, self-service resources, office hours for questions), the champion network (power users in each department who help colleagues), and the feedback loop for capturing and addressing adoption issues.

6. **Cutover Execution Plan**: Design the detailed cutover plan. Cover the pre-cutover checklist (everything that must be in place before the switch), the cutover weekend timeline (hour-by-hour plan for the technical migration), the post-cutover monitoring (what to watch for in the first 48 hours), the rollback criteria (what would trigger reverting to the old system), and the hypercare period (typically 2-4 weeks of enhanced support after cutover).

7. **Post-Migration Optimization**: Plan the optimization phase after migration. Cover the 30-day review (what is working, what is not), the data quality audit (verifying all data migrated correctly), the integration health check, the user adoption metrics (are people actually using the new system?), and the process refinement based on real-world usage.
