NOTE: Please be sure to backup whole project including database before upgrading ACEN to the latest version

STEP 0:  Before installing latest build be sure to uninstall old ACEN files from your local computer (by default these are installed in '\Program files' subfolder) by running ACEN uninstall application. Once this is done install the latest build.

STEP 1: Identify your existing activation center version (version information is available in admin dashboard)

STEP 2: Identify required database upgrade scripts. 

All SQL scripts are located in /database sub-folder. All scripts are named accordingly to ACEN version.

For example, upgrade script for upgrading database from 3.10.00 to 3.20.00 version is named: 3.10.00-3.20.00.sql

You need to run upgrade scripts on your acen database, one by one, starting from the oldest one.

Be sure to set correct database name in each script if your are not using default database name (acdb).

STEP 3: Preserve original /conf/acen.config file in order to save your existing acen settings.

STEP 4: Delete previous version of ACEN and install new update (copy folders from latest acen installation folder).

STEP 5: Restore previously saved original /conf/acen.config file.

STEP 6: Review whatsnew.txt document and make required changes (if any) to configuration files:

- web.config (set original culture information if you were using custom culture information and not default one)

- acen.config (acen will automatically add new options and their default values to this configuration file)
