Upgrading to a new version of ZDN (usually released about every 6 months or so) is recommended to get all the latest features and bug fixes. If you have not yet added any data to your old version of ZDN, simply delete the old version and download the latest version. But, if you have started entering data, then:

Upgrading the software involves:

1. Download the newest ZDN version from the website
2. Follow only the “Install” section of the installation instructions.
3. Move your old datafile from your old “ZDN Support Files/Datafiles” folder into your new “ZDN Support Files/Datafiles” folder.
4. Move any images or templates you’ve added from your old images (or templates) folder to the new one
5. Finish with the “Configure” section of the installation instructions, linking to your new folder and your newly updated datafile, but see the notes below for some version-specific details.
6. If you have a very old version of the “Busch Gardens Animal Diet Database” or earlier versions of Zoo Diet NaviGator, contact Heidi for help upgrading.

Upgrading from v2.1 or 2.2 to current version

• In ZDN:
  • Open up the new version of ZDN
  • Go to Settings (or the Settings Setup pop-up that appears if no datafile is linked yet) V2.2 and later: click the “update datafile” button.
  • Follow the steps to the copy of your datafile in its NEW location (BUT click “NO” when asked if you want to load the new file. If you do accidentally click Yes, cancel out of all the errors and repeat this step.)
  • Click the “Update datafile Part A” button and follow the pop-up instructions carefully.
• In the datafile:
  • Click the “Update Datafile Part B” button.
  • Quit the datafile
• Reopen ZDN, and relink it (in Settings) to your updated datafile.

Upgrading from 2.3 to current version

Note – you do NOT need to go through the upgrade process above to upgrade your datafiles from 2.3 to 2.4.

Tips and tricks:

• Quirks:
  • Depending on your updating process, you may run into issues with the NUTR_DEF table. I changed the name of “BGT_Name” to “Local_Name”. If you get a message about this:
    • Open up your datafile (make sure you and everyone else using it has quit ZDN first)
    • Press [F11] to show tables (if they aren’t already showing down the left side)
    • Open up “NUTR_DEF” table
    • Either:
      • Select the column called “BGT_Name” and copy it to the “Local_Name” column
      • or
      • Rename the column called “BGT_Name” to “Local_Name” (right click on NUTR_DEF and choose “Design View”)
    • While you are there, “Compact and Repair” (Database Tools  > Compact and Repair) the datafile.
  • Even once you do that, you might run into issues with calories and some other nutrients not showing up in the analysis. If this is the case:
    • Download the latest version and open the samplezoo datafile.
    • Open your datafile
    • Arrange the two windows so you can see both
    • Open the NUTR_DEF table in both windows
    • Drag the columns around until they match each other
    • Delete everything from NUTR_DEF in your file
    • Copy and paste everything from the SampleZoo NUTR_DEF table into your table.
    • Compact and Repair (Database Tools  > Compact and Repair) the datafile.
    • If you get a message about deleting relationships:
      • Open Database Tools > Relationships
      • Find the NUTR_DEF table and delete all the lines that go to it
      • Try the above steps again
      • Email Heidi if you have trouble – this can get tricky.
