From WL-500W to RT-N16

Due to an hardware fault of my WL-500W, in the next days I'll replace it with a new RT-N16.
I was running WL500W-1.9.2.7-rtn-r4051.trx, and I'll flash RT-N16-1.9.2.7-rtn-r4051.trx.

Is it possible to save settings.cfg and flashfs from my old router and upload it on the RT-N16 (I know of different flash size) ?

Thanks
