The original 15.2(4)E10 was released a while ago. The -UPD- variant typically addresses:
Supports both IP Base and IP Services feature sets. Licensing determines the activated features. Version: 15.2(4)E10 (Release Software). Supports LAN Base, IP Base, and IP Services
The most common cause of upgrade failure is a mismatch in software encryption capabilities:

: Indicates a "Universal" image containing all feature sets (IP Base, IP Services, Advanced IP Services). Access to specific features is controlled via software licenses. The "k9" designation confirms support for strong cryptographic encryption (SSH, HTTPS, SSL).
image, your switch's active capabilities (like advanced Layer 3 routing) will depend strictly on the software license activated in your hardware, not just the image itself. Cisco Community Best Practices for Deployment MD5 Verification:
For network administrators, the path forward is clear: if your legacy 3560 is running an older 12.x or early 15.x version, upgrading to 15.2(4)E10 is highly recommended. If your switch is already running a stable version of 15.2(4)E, there is little benefit to upgrading to a newer version and potentially exposing it to new bugs.
If your Catalyst switch was previously running an evaluation model or an unencrypted software image (indicated internally by an designation), it may reject the K9 variant during the initial boot sequence. The switch hardware will actively halt the boot process if it discovers a conflict between export regulations and licensing restrictions. To remedy this, confirm that a valid cryptographic licensing payload is active on your hardware architecture before attempting the transition. 2. Flash Size Truncation
