Migrating from legacy HPE Aruba Networking OS-Switch platforms to AOS-CX requires administrators to become familiar with different command structures, configuration models, and operational workflows.

Option B is appropriate because a cross-platform CLI reference guide enables engineers to compare commands used by AOS-CX, OS-Switch, Comware, and Cisco IOS.

This assists with translating familiar configuration and troubleshooting procedures into the equivalent AOS-CX commands.

For example, differences in VLAN configuration, interface management, link aggregation, routing, and diagnostic commands can be addressed through structured command comparisons.

Option D is correct because AOS-CX supports user-defined command aliases.

Aliases allow administrators to create shortcuts for frequently executed commands, reducing typing requirements and simplifying repetitive operational tasks.

HPE's AOS-CX CLI documentation explicitly supports the alias command and allows multiple commands and parameters to be incorporated into an alias definition.

Option A does not identify a specific command-transition mechanism.

Option C, CLI Bank, is also a legitimate HPE Aruba Networking command-reference resource. It provides command documentation for AOS-CX and other Aruba platforms, making it useful for training and troubleshooting.

However, for the intended two-answer selection, the cross-platform reference guide and CLI aliases are the more direct transition aids.

Official HPE Reference: HPE Aruba Networking AOS-CX Command-Line Interface Guide — Alias Commands; HPE Aruba Networking CLI Bank.

Verification note: Option C is also a valid learning resource. The distinction between B and C depends on whether the question is testing direct command translation or general command-reference access.
