How to Plan a Cloud Migration When a Vendor Uses IP Allowlisting

A move can change outbound addresses and break connections to vendors that allow only known source IPs.

Checks to make

Inventory integrations and allowlist owners, identify stable egress requirements, and coordinate updates before cutover. Test from the target environment and keep a monitored transition path; do not broaden allowlists beyond required addresses.
