Executive service questions

Questions leaders ask before approving CRM Migration

This section is written for decision-makers who need to understand the business reason, risk, first step and expected outcome before approving a CRM, data or automation engagement.

Why should leadership prioritise this now?

CRM Migration should become a priority when the current process is limiting revenue visibility, slowing execution or forcing teams into manual workarounds.

  • Leadership cannot get trusted answers quickly
  • Teams rely on spreadsheets outside the CRM
  • Data, reporting or workflow issues are now affecting growth

What is the executive risk of waiting?

Waiting usually increases hidden cost because poor process and data quality compound across reporting, automation, migration and user adoption.

  • Fear of losing 5 years of history
  • Duplicates arrive in the new platform
  • Go-live window too tight

What should a strong vendor plan include?

A strong plan should connect business goals to architecture, process design, data ownership, implementation sequence, QA and adoption.

  • Current-state diagnosis before build
  • Target operating model and implementation roadmap
  • Validation, reporting and adoption checkpoints

When should a CRO, COO or CRM Director approve this?

Approve the work when the business problem is clear, the cost of inaction is visible and the scope can be tied to revenue, efficiency or governance outcomes.

  • The business owner agrees on the desired outcome
  • The current setup is blocking decisions or execution
  • There is a realistic roadmap and delivery model

What should the first 30 days deliver?

The first 30 days should deliver a decision-ready plan, not vague recommendations.

  • Discovery workshop and system review
  • Risk-ranked issue backlog
  • Implementation roadmap with owners and priorities

What information should you prepare?

Prepare enough context to explain the business impact, current technical state and decision process.

  • Current platform and reporting pain
  • Known data, integration and adoption issues
  • Stakeholders, timeline, budget stage and constraints

Use these answers to decide whether this page matches your current CRM problem. If it does, ask Celumai for a focused audit and implementation plan.

Business challenges

Why CRM Migration projects fail

01

Fear of losing 5 years of history

Customer records, activity history, attachments, and custom fields -- all at risk if migration is done without proper mapping and validation.

02

Duplicates arrive in the new platform

Dirty source data migrated as-is. Thousands of duplicates land in the new CRM on day one, immediately breaking trust in the new system.

03

Go-live window too tight

Migration day becomes a crisis. No rollback plan. Business runs blind for 48 hours while the team scrambles to fix data issues.

04

Integration breaks post-migration

ERP, marketing, and support integrations all need reconfiguration. Nobody planned for this. The project runs 8 weeks over schedule.
