STOP! Before you begin the migration process:

Please check the Supported Platforms to confirm the latest requirements. Note that v11.0.x is certified on OpenJDK (11.0.10).
- IMPORTANT: Check that your frevvo database is a supported version; v11 will not work on some older unsupported versions.
Please read and understand the Planning for v11.0 which may require your action before you begin your upgrade. Note that v11 includes changes introduced in v10.2 and v10.3. There are important migration considerations to review before you upgrade.
The v11 upgrade will take longer than previous frevvo upgrades due to significant model migration. Please plan for frevvo to be unavailable for up to an hour during your upgrade.

v11 License Key Required

A v11 license key is required for this version of frevvo if you are upgrading from a prior version. Request a v11 license by completing this form before you begin the upgrade.

Determine Your Upgrade Path

Your frevvo Version	Recommended Upgrade Path to v11.0.x
v9.0.x	Upgrade to v10+ (see v10.0 Upgrade Guide), then upgrade to v11.0
v10.0.x, v10.1.x	Upgrade directly to v11.0

Note: Upgrades from frevvo 6.3.9 - 6.3.12 through v7.4.x are supported but these versions are not available for general release.

Migrating from HSQLDB

frevvo does not support the use of HSQLDB for use beyond demo/trials of the frevvo software. If by mistake you continued to use the demo/trial HSQLDB database for production use, you will need to first migrate your data to one of frevvo supported production databases BEFORE you can upgrade to later versions of frevvo.

Please follow the instructions on this page to perform your upgrade.
