We are running into issues performing a test of the Web Viewer database export process. When I select the Export option it does not allow me to select a folder where the DB/XML file is to be exported.
Output Management Web Viewer 12.1
You can't specify a download location when exporting your Web Viewer DB tables (at least not in Chrome you can't). The good news is that the table export still works. However the messages you get during the Export process are confusing. It says you can choose a file location for your "(Repository)" export XML file, but it winds up writing it to your Downloads folder, regardless.
Depending on how many tables you selected, you have to continue clicking Next button until you've exported your last table. After you "Finish" with the Export utility on the one Web Viewer server, all that's left to do is to move the .XML files you just generated, to the other Web Viewer server and import them. Fortunately, the Object Admin Import does allow you to specify the XML file location.
You may have to continually resize the window or thumb-scroll down to see your next options.
