This section describes changes to consider when you migrate from Office Word 2007 to Word 2010.
The default file format has not changed in Microsoft Office 2010. The XML-based file format was introduced in the 2007 Microsoft Office system and continues to be used. For a review of the XML file format, see Overview of the XML file formats in the 2007 Office system (http://go.microsoft.com/fwlink/p/?LinkId=182085).
When you open a document in Word 2010, it will open in one of three modes:
-
Word 2010
-
Word 2007 compatibility mode
-
Word 97-2003 compatibility mode
To determine which mode the document is in, check the document’s title bar. If (Compatibility Mode) appears after the file name, the document is in either Word 2007 compatibility mode or Word 97-2003 compatibility mode. You can continue to work in compatibility mode or you can convert your document to the Word 2010 file format.
-
Click the File tab.
-
Perform one of the following:
-
To convert the document without saving a copy, click Info, and then click Convert.
-
To create a new copy of the document in Word 2010 mode, click Save As, type a new name for the document in the File name box, and then click Word Document in the Save as Type list.
-
Click Info, and then click Convert.
Compatibility Checker
The Compatibility Checker lists elements in a document that are not supported or that will behave differently in Word 2007 or in Word 97-2003 format. Some of these features will be permanently changed and will not be converted to Word 2010 elements, even if you later convert the document to Word 2010 format.
Embedded Word 2010 objects
Open XML embedded objects can be converted to enable users on earlier versions of Word to be able to change them.
-
Right-click the embedded object.
-
Point to Document Object, and then click Convert.
-
In the Convert dialog box, click Convert To.
-
In the Object type list, select Microsoft Word 97-2003 Document.
Equations
If you save a document in Word 97-2003 format, equations will be converted to images that you cannot edit. However, if you later convert the document to Word 2010 file format and no changes have been made to the equation images in an earlier version, the equations will become text and you will be able to change them.
SmartArt graphics
When you save a document that contains a SmartArt graphics in Word 97-2003 format, the graphics will be converted to static images. You will be unable to change text inside a graphic, change its layout, or change its general appearance. If you later convert the document to Word 2010 format and no changes have been made to the images in an earlier version, the graphic will be changed back to a SmartArt object.
Migration considerations from Office 97-2003 to Office 2010
Many of the changes from Office 97-2003 to Office 2010 are no different from Office 97-2003 to the 2007 Office system.
For a list of migration considerations from Office 97-2003 to the 2007 Office system, see Migration considerations for Word 2007 (http://go.microsoft.com/fwlink/p/?LinkId=182089).
The following changes in Word 2010 might affect migration:
-
AutoText is being moved back to Normal.dotm to facilitate autocomplete. For users going from Office Word 2003 to Word 2010, we recommend that you move the document to %AppData%\Word\Startup, and then follow the steps to upgrade a document. Office Word 2007 users will find their autotext automatically moved.
-
AutoText gallery is now available in the Quick Parts gallery. Therefore, users no longer have to remember to move their autotext to the Quick Parts gallery.
-
Word will automatically migrate building blocks to Word 2010 when you first start the application. This is done by creating a copy of the existing building blocks file and putting it in a new directory, %AppData%\Document Building Block\{||cc}\14, and the striping the building blocks that were provided with Office Word 2007 from the file.
-
Similarly to Word 2007, Word 2010 gives you a new Normal.dotm on the first start. Your old normal file will be named normalold.dotm. If you want to restore your setting from Word 2007, right-click the file, and then click Open. Once in Word, you should use the Convert button in the Backstage view to convert the normal file to Word 2010 format.
VBA settings migration
In Office 2010, Visual Basic for Applications (VBA) 6.0 was updated to VBA 7.0. VBA 7.0 settings were reset to their defaults after migration instead of automatically repopulating. This occurred because the registry settings for VBA are in a different hive in Office 2010, as shown in the following table.
|
Version
|
Registry subkey
|
|
Office 2000 through Office 2007
|
HKEY_CURRENT_USER\SOFTWARE\Microsoft\VBA\6.0\Common
|
|
Office 2010
|
HKEY_CURRENT_USER\SOFTWARE\Microsoft\VBA\7.0\Common
|
To correct this problem, copy the VBA 6.0 registry keys from the 6.0 hive to the 7.0 hive.
