I know that the 1040 requires upgrading to 4.1.4-GR1-P3 prior to loading 5.x code, but the same was not explicitly said for the 1030. It may be worth a try, though. ---

Only the 1030S is supported on v5.2…if you just have the 1030 model, it may or may not work. [https://documentation.a10networks.com/ACOS/520x/ACOS\_5\_2\_0/pdf/A10\_5.2.0\_RN.pdf](https://documentation.a10networks.com/ACOS/520x/ACOS_5_2_0/pdf/A10_5.2.0_RN.pdf) Page 171 ---
