The best way is to contact us and we'll help you with the upgrade process.
Easysoft ODBC-ODBC Bridge upgrades require a new license, so don't upgrade an existing licensed ODBC-ODBC Bridge server until you have got a new license.
Generally speaking, you don't have to upgrade your ODBC-ODBC Bridge server just because you've upgraded your ODBC-ODBC Bridge client or vice versa. If you're concerned about compatibility, contact us before upgrading.
