As pointed out by @alagoutte you can't simply export a Cisco IOS NOS based Switch's configuration and import (copy) it - as-is - into an ArubaOS-Switch NOS based Switch...Cisco and Aruba (HP/HPE/Aruba) don't use the same NOS Network Operating System (it's a matter of Cisco IOS versus ProVision/ArubaOS-Switch).
You need to examine your actual configuration and try to replicate it by adapting (for what is possible) its commands to cope with ArubaOS-Switch equivalent ones.
There is a nice guide that help doing so. Check it here or here (and also one a little bit older here).
A brief (but interesting) presentation about how Cisco and HP/HPE/Aruba approach VLAN tagging and Port Aggregtion their own way is here.
