(From v.7.x)
Back it up! Please make a backup of the following important files before proceeding (you might need them later, even if nothing goes wrong here):
Get the files. The file you downloaded should be called tngupdate7x-712.zip. Extract or "unzip" the files included in tngupdate7x-712.zip to a temporary location on your hard drive. Some files should extract into subfolders called 'admin', 'English', 'googlemaps' and 'special'. There will also be folders containing updated files for some of TNG's prebuilt templates, and a folder for each language TNG supports.
Upload them. Copy all files in the admin, English and googlemaps folders to those same folders on your web site. Copy all files not in a folder to the main TNG area on your web site. For many of you, that will be the "public_html" folder. Be sure to overwrite existing files that have the same names.
If you support other languages, also upload the files for those languages (also included in the update zip in their respective folders) to the proper folders on your site.
Open this readme file from your site. If you previously opened this file from your local computer, close it now and open it again from your web site. It should be among the files you just uploaded.
Update the database structure. In your web browser, run the script admin/dbupdate7x-710.php (or just click the link). The file should now be in your admin folder. You will be asked to log in at this point if you haven't already. This operation will open a new window and make a few database structure changes. Your data should not be affected. You will see a short list of messages detailing what is being done, as well as a message when the script has finished. When this step is complete, it is recommended that you delete the admin/dbupdate7x-710.php file from your web site.
NOTE: Because this database update is compatible with several incremental versions, there may be some commands that have already been done, so don't be alarmed if some lines say "failed or done previously". No database changes were made between versions 7.1.0 and 7.1.2.
tngrobots.php. This update contains an update to your tngrobots.php file (NOT robots.txt, which is something completely different) in the 'special' folder. If you haven't ever made changes to your tngrobots.php file, just upload this file to the main TNG area on your site (overwrite the existing file). If you have made changes to your tngrobots.php file, you may want to merge your changes into this new file before uploading it.
The update should be complete. You did it! Before closing this page, please read the notes below.
NOTES:
New Settings. New options have been added under Chart Settings, Import Settings and Map Settings. Default values will be used if you don't change them, but you might want to take a look. Read the Help screens attached to those pages for more information.
Templates. Some template files have been updated, and the new files have been included in the 7.1.2 zip in the various "template" folders. You should only upload them "as is" if you have not made any changes to your template files. If you have made any changes, I recommend that you instead take note of the changes in the new files and merge those with your changed files.
