Hi,
1. Open servers and vms- there's an option to work with VMs and open servers using R82 for labs testing, demo etc... not for production.
Just need to make sure we connect eth0 to mgmt network and eth1 to Sync network. For VM it might be you will need to adjust some security settings on the vSwitches if gateways are not auto discovered. Official support is on roadmap and will be released later on with JHF or R82.10
2. Migration tool from Cluster XL to ElasticXL and clusterXL vsx to ElasticXL VSNext - Tool will be available close to R82 GA release.
Regards,
Shai
