Preliminary Notes

Multiexcerpt
MultiExcerptNameupdate_notes
  • Bridge 7 The BRIDGE installer will check your Bridge license. When updating a BRIDGE to a new version (e.g. BRIDGE 6 to BRIDGE 7), you need to apply the new license before updating the system.
    Otherwise the installer will complain about a license mismatch: "Your current license version '<your old version>' is not valid for upgrading to Bridge version '<target version>'. Please update the license first and run the update installation again."

  • As of Bridge 7, the BRIDGE uses Apache 2.4. You can find information on behavior changes on the Apache pages.

    Note

    If you have modified the Apache configuration as described on Configuring the Proxy, you may need to apply your changes to the new Apache templates that have been provided with the update. Please refer to the mentioned page for more information.

  • Bridge 7 If you are updating an older installation (e.g. BRIDGE 6), your BRIDGE and/or proxy certificate might still use the MD5 algorithm. This algorithm is insecure and deprecated and is not accepted by BRIDGE 7 installations anymore.

    Note

    Before updating your BRIDGE, make sure that both certificates are using a secure algorithm, e.g. SHA256. How to update the certificates is described on Managing the Bridge Certificate and Managing Bridge Proxy Server Certificates pp.

 The Update Process

  1. First, stop all running services of the former BRIDGE installation in the administration UI to make sure that all Bridge processes are terminated. This ensures that all services will be restarted by the new BRIDGE after its installation.
  2. Stop Windows service "E2E Console", too (Start > Control Panel > Administrative Tools > Services).
  3. Start BridgeInstaller-win32-64-7.x.x.jar to start the installation of the BRIDGE.
