When It May Be Better to Delay the Upgrade

While upgrading is generally beneficial, some situations may require additional preparation before migrating to TYPO3 v13.

Many upgrade issues occur because important preparation steps are skipped. Avoiding these common mistakes can help ensure a smoother TYPO3 upgrade process.

Upgrading Without a Backup

A backup is essential before performing any CMS upgrade.

• Always create a full backup of files and databases
• Verify that the backup can be restored if necessary
• Keep multiple backup versions if possible

Skipping Staging Environment Testing

Testing upgrades on a live website can lead to downtime and unexpected errors.

• Always perform upgrades in a staging environment first
• Test system functionality before deploying changes
• Fix issues in staging before applying updates to production

Using Outdated Extensions

Extensions that are no longer maintained can cause major compatibility issues.

• Review all installed extensions before upgrading
• Update extensions to versions compatible with TYPO3 v13
• Replace unsupported extensions with maintained alternatives

Ignoring System Requirements

Running TYPO3 v13 on unsupported environments can lead to performance or stability problems.

• Verify PHP and database compatibility before upgrading
