Additional Notes:
1.	Firmware Naming Convention: 
o	Aruba uses celestial or mythological names (e.g., Orion, Pegasus, Hercules) to designate firmware trains specific to hardware platforms. Each train is tailored to the chipset and capabilities of the associated AP models.
o	The firmware name is typically prefixed with ArubaInstant_ followed by the code strain (e.g., ArubaInstant_Vela_8.9.0.x_xxxx).
2.	Support and End-of-Life (EOL): 
o	Older models (e.g., IAP-104, IAP-105, IAP-175, RAP-3WN, RAP-108, RAP-109) are no longer supported in newer firmware versions (e.g., post-6.4.x or 6.5.x).
o	Models like IAP-204, IAP-205, and IAP-205H are unsupported from Aruba Instant 8.3.0.0 onwards.
o	Models like IAP-214, IAP-215, IAP-224, IAP-225, IAP-274, IAP-275, and IAP-277 are unsupported from 8.7.0.0 onwards.
o	Models like IAP-207, IAP-324, IAP-325, IAP-334, IAP-335, and AP-387 are unsupported from 8.11.0.0 onwards.
3.	Firmware Versioning: 
o	Firmware versions are structured as ArubaInstant_<CodeStrain>_<Version>_<BuildNumber> (e.g., ArubaInstant_Vela_8.9.0.0_xxxx).
o	Check the HPE Aruba Networking support portal or release notes for the latest firmware versions and supported models.
4.	Mixed AP Deployments: 
o	In a mixed Instant cluster, all APs must run compatible firmware versions. If combining models with different code strains (e.g., Vela for IAP-207 and Pegasus for IAP-109), the Virtual Controller will attempt to downgrade or upgrade APs to a common compatible version, which may limit features.
o	Ensure region codes (e.g., US or RW) match for meshing and seamless operation.
5.	Sources for Verification: 
o	The list is compiled based on information from Aruba Instant release notes and community resources.
o	For the most up-to-date list, consult the HPE Aruba Networking support portal or the Aruba Instant Release Notes for specific firmware versions.
Limitations:
•	Some newer models (e.g., AP-615, AP-635, AP-655, which support Wi-Fi 6E) may use different firmware trains not listed here, as they were introduced after the provided data (up to 2023). Check the latest release notes for these models.
•	If you need firmware for a specific model or version, you may require an HPE Aruba support account to download images from the support portal.
If you need assistance finding a specific firmware image, verifying compatibility for a mixed AP setup, or guidance on upgrading/downgrading, let me know!
