Unlink and clear template

[Anonymous12247]

Hi ! I'm new to zabbix.

Recently I upgraded zabbix 3.0 to 4.4 and updated template as well.
There is error when I unlink template and try to use new template, so I unlink and clear.

Is it possible to get back my historical data from old template ?


Thanks.

Sorry man, but the data is gone because the "unlink and clear".

In updates, templates need to be manually checked and updated if you don't want to lose data.
