Kevin,
If you are using ARCHIBUS v12, and your important features are interaction with AutoCAD, ability to customize, asset mgmt, and reporting, you should stay with ARCHIBUS.
Let me explain why...
- most important, your data. As Steve mentions in another reply, there is no migration needed to gor from v 12 -> v 15 unless you need to incorporate the newer security features, the newer activities and/or Web Central.
- just as important to your data is your time (and that of the other users of the system). The is 0 learning curve when going to the newer version. As with AutoCAD upgrades, you can continue using AutoCAD the way you always have whenever you upgrade... and as you stumble upon the new capabilities, slowly start to make them a part of your work process. Same with ARCHIBUS, the navigator doesn't change, though there are newer interfaces available (Process Navigator for example), reporting doesn't change, basic functionality doesn't change... although there are a number of cool new user interface improvements. Bottom line, no loss of production time.
- integration with AutoCAD? I may be biased, but with the ARCHIBUS API tools available with the product, there isn't anything, and I mean ANYTHING, that cannot be accomplished, if the need is there. In my opinion, the integration with AutoCAD is 2nd to none.
- Customization? Heck, about the only thing you can't customize in ARCHIBUS are the core pull-down menus and the font style in the menus. You, the user, have control over the navigation Menus, unlimited ad-hoc reporting, unlimited custom table & field creation (from within the application... no need for a DBA to get involved), easy built-in import/export to Excel, short-cut creation...
- Asset Mgmt? it's all there in the Fruniture & Equipment module. Standards, audit surveys, warranties, leases, etc.
