HP Procurve Switch Backup and restore config to a different version.

[searching1]

Hi,

We do have existing HP Procurve running version U.11.08 and I backed it up into the spare one HP procurve 2510G-48 running Y.11.16.

After several trials the result was still a faillure.

1. upload U.11.08 existing configuration to Y.11.16 - 00000 Error invalid File 

2.download first the exisiting starup from Y.1.1.16 and edit, paste the conficuration from U.11.08 and change the product id. - Line 0-416 Invalid input.

3. Tried just a copy and paste from cli but some command didnot match,

any suggestion or do i need to convert first my spare switch versiton from Y... to U.11.08? Since according to HP realease U version is only for HP procurve model(j9020A) and Y is only for model J9279A & J9280A?

I would like to ask how can I upload the config from J9020A ver U... to J9280A version y...?? any solution for this?

Thanks
