Refactor template without loosing data

[ghoz]

Hi, I just tried moving a few items from a template to another one, and i lost all my historical data ...

Is there a recommended way to do that ?

Unlink one template, but just unlink (no unlink and clear!) and then link your host to another template. Existing items will be reattached to the new template automatically.

Thank you...

So in my case I have a "catch em all template" that i want to split in 2,
I have to
* unlink the template without clearing data
* refactor the huge template in two templates
* re link , and it should work, right ?

I dont have a testbed as i'm already working on a prototype... beter be sure :-)

for reference, what I did was
* copy the items from the big template to the new template
* remove the items from the template <= bad move
* link to the new template <= nodata ... duh...

anyway I only lost last day of data, I exercised my sql-fu a bit to partialy restore the data from yesterday's backup...

It should work. Note that these operations may take a while depending on the number of hosts linked to your templates. Please consider having a test environment some day.

sure will do ...
but for now it's not yet in production, but it's already of great use...
