Concern No. 4: Access security. Microsoft Access 2007 no longer uses Object Level Security (also known as Workgroup Security). Companies that use Object Level Security on their Access databases will need to redesign their security model to use the new features in Microsoft Access 2007.
Concern No. 5: Training issues. Users already know how to use Office 2003. The new user interface in Office 2007 will require training to reach the same level of proficiency.
Concern No. 6: Inconsistent user interface. The new ribbon feature isn't available in all Office apps. Most users prefer a consistent user interface across all Office applications.
Concern No. 7: No more Excel writing in SharePoint. Excel 2007 no longer allows users to write to lists contained in SharePoint; users can only read the lists. (With Excel 2003, users can both read and write lists in SharePoint 2007.)
Concern No. 8: Equation compatibility issues. The equation editor in Word 2007 is incompatible with Office 2003 and previous versions.
Concern No. 9: Useless DAPs. With Access 2007, it is not possible to create or modify existing Use of Data Access Pages (DAPs), as you could in Microsoft Access 2003 and earlier.
Concern No. 10: Lotus and Exchange challenges. The user interface to import files from Lotus 1-2-3/DOS and Exchange has been removed from Access 2007.
So there it is, folks. Now if you are thinking, "What?! Those are the best top 10 reasons not to upgrade? No proclamations of Office Armageddon?" then we are on the same page. There are certainly fine Office-like products on the market (such as OpenOffice and others), but if your crew prefers Office, then let them evolve with Office 2007. Whatever issues may be in your path, there are ways around all of them. At times, you may be able to find a solution from Microsoft or a third-party migration assistance company. Regardless, don't let these issues be stumbling blocks that trip you, but rather stepping stones that propel you forward.
What do you think? Is 2009 the year you upgrade, switch to OpenOffice 3.0, or simply stay put with a legacy set of Office apps?
