Problems with discovery...

[Alfista]

I have now installed a new appliance of Zabbix 3.4.5.
I have there imported my Templates and Hosts, but after that I found that some parts wasn't exported from the old one and imported to this new one. It was all parts which was based on or better to say was found by the auto discovery system (items, trigers and graphs).

And I have now to questions:
1. How is possible to restart the discovery function only on some hosts, that they found and add the parts that I miss
2. When I have creted a new discovery rules, it found only some machines and not all. I have created two discovery rules for two VLANs and on all is set that it should discover over SNMP and Zabbix Agent. And the result was finding only PC running ZBX Agent.

Please can anybody help me?

Thanks
