<p class=MsoNormal>I was just asked by a client how to convert a newly created
GDB in ArcGIS 10 to one that could be read by ArcGIS 9.3. Before 10, I would
normally do this by moving everything to a personal GDB and editing the GDB_ReleaseInfo
table to have the values the older versions expected to see. This always worked
great as long as your GDB was fairly simple without a lot of higher end
features such as geometric networks or parcel fabrics.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>ArcGIS 10 however has completely revamped the personal Geodatabase
schema so the GDB_ReleaseInfo table does not exist and I have not been able to
find a table that contains similar information. So this method will no longer
work for converting back to older versions. ESRI recommends if you want to
convert to an older version, you should create a new GDB using an older version
of the software. Then copy and paste the data from the ArcGIS 10 GDB to the
newly created older version GDB from an ArcGIS 10 install. This is great if you
have a computer installed with the older version but what do you do if you don’t.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>One option I found is to create layer packages. When
creating a layer package it has the option to create one that is compatible
with older versions of ArcGIS. Here is a link to the online help with more
information. If anyone else has ideas or methods they use I would be interested
in hearing them.<o:p></o:p></p>
