For all other cnMatrix models (EX10xx, EX20xx, TX10xx, TX20xx, EX30xxR-P), we are using:  
**cnMatrix\_6.1.2-r4\_EX10xx\_EX20xx\_TX10xx\_TX20xx\_EX30xxR-P.tar.gz**

I’ve seen a few discussions around recommended upgrade paths, specifically stepping through 5.0.3-r4 before going to 6.x.

So far, I’ve upgraded a handful of switches from **4.4-r3 → 6.1.2-r4 directly** with no issues observed (config retained, no immediate operational problems).

However, we are preparing to upgrade ~500 switches and want to follow **official Cambium guidance** before proceeding at scale.

**Questions:**

- Is a direct upgrade from 4.4-r3 → 6.1.2-r4 considered safe/supported?

- Is stepping through 5.0.3-r4 still recommended or required?

- Are there any known edge cases (cnMaestro, config migration, credentials, etc.) that would make a staged upgrade safer?

Looking for confirmation before proceeding network-wide.

@TamN Do you have any guidance on this?
