What this guide helps you evaluate
Engineering and finance teams budgeting a database move to AWS, Google Cloud or Azure.
Prepared by the PROFENG Editorial & Engineering Team. This page is designed to help you compare the moving parts, organize due diligence and ask better questions before you commit money, sign a contract or change an operating process.
What to compare first
- Migration service charges and replication compute
- Network egress from the source environment
- Temporary dual-running of source and destination
- Destination database compute, storage, backups and I/O
- Engineering labor, testing, downtime and rollback capacity
Step-by-step process
- 01
Measure database size, change rate, peak load and required downtime.
- 02
Classify the migration as homogeneous or heterogeneous.
- 03
Use each provider's current migration and destination pricing calculator.
- 04
Budget a period where both environments run simultaneously.
- 05
Run a pilot and record actual transfer rate, replication lag and destination resource usage.
Common mistakes and risk checks
- Comparing migration-tool fees while ignoring the destination database bill.
- Assuming data transfer is free in every direction and region.
- Under-budgeting application testing, schema conversion and rollback.
