Proper Thold upgrade instructions

[hid3]

Hello everyone.

Any ideas why does Thold README lacks instructions about how to upgrade from previous Thld versions?

What I tried was download the newest version of Thold, disable & uninstall the plugin via Plugin Management, move the old thold directory to safe place and install the newest directory. Install/enable via Plugin management. However, during the installation of the plugin it gave some PHP errors (didn't manage to catch them). After this I realised my thold database is gone!!! Thankfully I had my old mysql dump so I managed to restore it. However, when restored, tholds didn't work. Besides, when viewing Thold section, I got much errors:
Notice: Undefined index: thold_warning_low in <my cacti path>/thold/thold_graph.php on line 531

So I reverted back to the old version... Any ideas?

There are too many forks of thold to provide accurate instructions. Basically you backup the old thold using tar, untar the current, and then click the thold tab followed by plugin management to verify version.

If that does not work, you'll have to dig into the upgrade script.

Thanks for brief instructions. One more question: Do I need to mess with something in 'Plugin Management' section before or after upgrade? E.g. Disable or Enable plugin, etc..

Thanks.

OK, I did as mentioned. I moved old thold directory (v0.4.4) to safe place and just uploaded the newest one (v0.4.8-3). I clicked on Thold tab. Everything looked nice. Then clicked on Console, Plugin management. It displays the new version in there. However, in Cacti log I just get Tholds:0 Hosts:0 although there should be much of them. Any ideas what's wrong?

Cacti 0.8.7g
PHP 5.2.6
MySQL 5.0.51

It's really not enough information for me to answer anything. Make sure that you don't simply rename the thold directory. This will break things.

I really move it to completely another place, on different disk mounted as /backups.

Oh, and forgot to mention this is on Linux Debian 6.0.2 and Cacti is patched with PIA 2.9.

What additional information (maybe some debug logs, etc) should I provide?

Thanks.

Does the thold_data table exist and does it contain anything at all ?

[hid3]

Yes, it exists and contains all of my tholds

try to run "php <cacti_path>/plugins/thold/extras/upgrade.php" from command line once.

i know this is an ancient post, but had similar issues. 0.4.1 -> 0.4.9. I had to run the upgrade.php script manually in the "extras" folder to get this to work out correctly (after moving the original thold dir, and extracting the tgz).

I wish it would be better documented in the README.

Thank you istein001... we've been struggling with a 0.4.2 to 0.4.9 upgrade and were losing all of our thold data. We ran the upgrade.php manually and it upgraded correctly and we didn't lose any of our data.

I agree that it was hard to find that you had to run this manually.

You shouldn't have to run it manually, it should check for the upgrade the next time you click on the thold tab.
