Generic etcd to Astra Migration

Pre-Migration

• Inventory client API usage (KV, Watch, Lease, Txn).
• Identify revision-sensitive consumers and compaction assumptions.
• Establish baseline latency and error budgets on current etcd deployment.

Migration Execution

• Use astra-forge compile or astra-forge converge depending on source format and tenancy strategy.
• Bulk-load into Astra with checksum verification.
• Shift clients using staged endpoint rollout.

Post-Migration Validation

• Key/value parity checks.
• Watch stream correctness and cancellation behavior.
• Lease grant/revoke/keepalive correctness.
• Error-budget adherence under representative load.
