======Produmex Scan Version Upgrade======

<WRAP center round todo 65%>Make sure that you check the [[implementation:scan:releasenotes|release notes]] of the new product version before starting the upgrade because it might contain important information regarding the upgrade.</WRAP>

=====1. Produmex Scan Add-on=====
The steps of a version upgrade for the Produmex Scan add-on are identical to a [[implementation:scan:installguide#install_the_produmex_scan_add-on_on_premise_or_in_sap_cloud|fresh installation]]. 

If you are upgrading from a version higher than 17.05, it is not required to uninstall the current version before starting the upgrade. 

When the add-on is started the first time after the upgrade, the database setup runs. \\

Note: To run the database setup, a database backup that has been created within an hour is required on an MSSQL environment.

All components have to be upgraded:

1. SAP add-on. Start the new add-on immediately. It may generate new objects in SAP

2. Server module. The installer has to be started on the computer on which the 
ServiceBroker is installed.

3. Client application


We put information in the release notes in case it is necessary to upgrade the ServiceBroker.
=====2. Produmex Service Broker=====

If you are upgrading from version 17.11 or higher, it is not required to install a new version of the Service Broker for an upgrade. 
If you are upgrading from a version lower than 17.11, take the extra steps described here: [[implementation:releasenotes:manufacturing_complete#version_1709|Version 17.09]]. 
The steps of a version upgrade are identical to a [[implementation:scan:installguide#install_the_produmex_service_broker|fresh installation]]. 

<WRAP round important>If you want to uninstall the 32-bit DI API when upgrading to the 64-bit Service Broker, it is recommended to uninstall both the 32-bit and the 64-bit DI API and then install the 64-bit DI API again because on certain SBO versions the uninstallation of the 32-bit DI API can cause issues for the 64-bit DI API.</WRAP>
