Upgrade path not available

Hi,

 

We have a CISCO1921/K9 with IOS file c1900-universalk9-mz.SPA.152-3.T.bin
We want to upgrade to c1900-universalk9-mz.SPA.157-3.M8.bin, latest release by cisco.

I checked the release notes but the link for the 1900 series routers isn't working.

Could I find this information somewhere else?

Page not show because may be due to end of Life.  ( i see all the end of life links broken)

I do not see any issue you can upgrade from 152 to 157.  ( Hope you have latest ROMMON code  15.0(1r)M9)

 

Follow below guide should work as expected :
