Terraform State Splitting: terraform state rm + moved Blocks

Splitting a monolithic 4GB Terraform state file into scoped microstates is one of the nastiest live-infrastructure challenges you'll face — here's how to do it without downtime using terraform state rm and moved blocks.

You'll learn:

• Why state files balloon past 4GB and why that breaks plan/apply performance
• How to use terraform state rm to surgically extract resources without destroying them
• Using moved blocks to re-home resources into child state backends cleanly
• Sequencing the migration to avoid drift, lock contention, and accidental deletes
• How to validate microstate integrity with terraform state list and targeted plans before cutting over
