SDM Upgrade on Cisco 851

The device has SDM Express right now and I need to upgrade it to the Full version. Router is running IOS 12.4.(4)T7. I have never done it before so I wanted to ask for some advice how to approach it.

What do I need to consider before starting the project?

Is it better to install it on the router or server, I understand it can be done either way?

I will backup the startup-config and IOS image.

Do I need to have a valid support from Cisco to download and install the update?

Thank you.

If CISCO SDM Express in present on the router it means your complete SDM is located on the router. In order to have it fully functioned you need to download the CISCO SDM from cisco website and then connect your router to it. Only then you will be able to perform full opertions. If it doesn't help you then in the SDM setup there is the option of install both on router + computer. Thus the SDM will be installed on your router.

SDM can be installed either on a PC or on the router.  I've had better luck installing it on a PC; sometimes the application does not run correctly from the router.

If you choose to install it on the router, you have the options of SDM Express only, full SDM + SDM Express, and full SDM only.  Sometimes full SDM or full SDM + SDM Express will not install on the router due to file system constraints.

You also need pretty unrestricted access to the router to get it to install correctly.  I've had difficulty getting it to install through a firewall, for example.  (I think it uses TFTP for the file copy; I could be wrong about that.)

Here's the link to download the setup:  http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm

Download SDM-V25.zip, extract it, run the setup program.

No you dont need any kind of TFTP to install SDM. Just login into the router and add the user with the command
username user privilege 15 password password.
Then install the SDM with this user and it will work.

I know that you don't need a TFTP application, but something blocks the installation when traversing a firewall, even when HTTP/HTTPS works.  I suspect that the setup program itself uses TFTP, or something other than the HTTP protocol to transfer the files.

SDM installation should not change anything, although you may have to enable HTTP with local login.
