ASR903: upgrade procedure (IOS-XE)

[o-evdokimov]

Hi, Guys

I have ASR903 with single RSP. IOS-XE version is 03.10.00.S.153-3.S

What procedure I will have to do for upgrade IOS-XE to the newer version. The "Installing and Upgrading Software" guide describes only ISSU procedure (with double RSP configuration):

Router# request platform software package install node file bootflash:/issu/asr903rsp1-adventerprisek9.upgrade.bin

... but I have only single RSP.

Copy the IOS to the appliance.  Change the boot string.  DO NOT REBOOT yet.  Upgrade the boot strap.  The bootstrap will cause a reboot.
