  • Do not proceed with the installation
  • Report any issues to the help desk immediately on 01964 503400 or see Getting support

Analysis Recalculations

• Following the upgrade the internally calculated analysis data may be recalculated to reflect any changes in the formula.
• These recalculations will take some time, depending on the amount of data, hardware specifications, etc.
• The system is available whilst these calculations are running, although users may perceive a slight performance hit. Depending on your available resources, you may prefer to wait until this has completed.
• If you want to allow user access during the Calculatoins, re-open port 8099 on the server if you closed it initially - otherwise wait until the calculations have completed.

• Calculations completed:

Rollback

In the event of a problem during the server upgrade, the roll-back process is as follows:

1) Contact EHS who will be able to supply files for the previous version of AquilaServer. 2) Use the Aquila Server Configuration tool to make a careful note of your settings. 3) Uninstall the AquilaServer product 4) Restore the database from the backup taken immediately before the upgrade process. 5) Install the previous version of AquilaServer as supplied, using the settings you noted in step 2.
