What is an important step when migrating between chaincode versions?

When migrating between chaincode versions, it is crucial to verify the upgrade completion before restarting. This step ensures that the new chaincode is fully functional and correctly integrated into the current network environment. Verification allows developers and network administrators to confirm that all necessary updates have been applied successfully and that there are no issues that could disrupt the operation of the blockchain network.

The importance of confirming that the upgrade is completed effectively mitigates risks associated with potential downtime or inconsistencies that may arise from an incomplete migration. In the context of blockchain technology, maintaining the integrity and reliability of the ledger during such transitions is essential for continued operational success.

In contrast, stopping peers without backing up could lead to data loss or complications if something goes wrong during the upgrade process. Ignoring ledger backups poses similar risks, as it prevents the recovery of critical data if errors occur post-upgrade. Updating channels without prior modifications could result in incompatibilities or disruptions, making it imperative to follow proper procedures and verification protocols during the migration process.
