# Upgrading to version 2

## **Report Caches**

Version 2 introduces a breaking change to historical cached data from installations before version 2.0.0. Therefore, when you're upgrading an Exivity version 1 to version 2, all Reports will be **automatically Unprepared** during upgrade. After completing the upgrade, you will have to browse to your **Report Definitions** and **Prepare** each of them for the appropriate date period:

## **Changes to Transcript**

As part of version 2, outdated syntax in your **Transformers** will be **automatically** converted to comply with version 2 Transcript syntax. Your version 1 Transformers will be backed up during upgrade into the default backup folder *%EXIVITY\_HOME\_PATH%/system/backup.* To manually upgrade any of your version 1 Transformers, you may use the script provided in *%EXIVITY\_PROGRAM\_PATH%/update-transcript-v2.0.0.bat* (this script will upgrade any Transformer currently available in the default Transformer folder).

## **Replacement of Exivity Eternity Service**

the service that was previously responsible for scheduling and execution of workflows ("Exivity Eternity Service" which ran eternity.exe) has been replaced by the **Aeon** component and runs as the "***Exivity Scheduling Service***". In case the "Exivity Eternity Service" was running under a non-system account, ensure to update the newly registered "Exivity Eternity Service" with the corresponding user service credentials.
