Do I need Maintenance or an Upgrade?


Maintenance gives you technical support and updates for 1 or 3 years. If you have ERwin and a current maintenance contract that is about to expire, you need to purchase maintenance. You must purchase maintenance BEFORE your current maintenance agreement expires, or you will be liable to pay for an upgrade.


If you have an older version of ERwin that is no longer under a support contract, OR you have a current version but wish to increase functionality (e.g. from Standard to Workgroup) you need to buy an upgrade. Upgrades include 1-year maintenance. Most of the upgrades available are not shown - please call us on 02 8880 5111 for more information.

ERwin DM Workgroup Edition

ERwin DM Workgroup Edition offers the same functionality as ERwin DM Standard Edition, plus a centralised model management repository, collaborative modeling with conflict resolution, and change management with audit capabilities. It is ideal for teams with multiple members who are working on models simultaneously and/or that need a change management function.
