Troubleshooting Frequently asked questions or FAQ. 1. Q: Can I flush/clear the queue (as depicted in Administration → Queue)? A: No. 2. Q: How do I migrate from one database to another? A: Dump data only --no-create-info), create the new database using schema files from Zabbix and import the data. 3. Q: I would like to replace all spaces with underscores in my item keys because they worked in older versions
