What may help you is the Cisco HPE CLI comparison guide: https://community.arubanetworks.com/t5/Education-Australia-New-Zealand/Updated-CLI-comparison-guide-Provision-Comware-Cisco-now/gpm-p/270981
Also, if you have problems converting your current Cisco config into HPE Aruba/Provision config it might help if you can post your current config on the Cisco side, at least the interface config, the vlan interface config and the routing config. That may people help to understand what is configured on the old switch and not on the new switch and prevents your clients network connectivity. My guess would be that on the current switches you have tagged VLANs (switchport trunk allowed-vlan) configured, and not on the new switches, where you go in the vlan, then use the tagged 10-18 command to tag the vlan on ports 10-18; which makes clients isolated from the network. It is the other way around, interfaces configured on the vlan, instead of vlans on interfaces; but you can achieve the same.
