DMM upgrade 5.2 > 5.4

[pratik.rb]

Hi Pros,

We are in process of planning an upgrade of DMM server from 5.2 to 5.4.

I have questions if someone can help answer...

1) We have existing MCS7835-H3 which is listed as supported by DMM 5.4. Does upgrade to DMM 5.4 have to involve installing it in VMWare or is it applicable only to fresh 5.4 installation.

I am assuming that 5.4 can be upgraded on current server without VMWare. Is my assumption correct?

2) Do I need to upgrade DMM server as 5.2 to 5.2.1, then 5.2.1 to 5.2.2, then 5.2.2 to 5.2.3, then 5.2.3 to 5.3 & finally 5.3 to 5.4 or can I directly upgrade from 5.2 to 5.4 or 5.2 > 5.3 > 5.4?

Upgrade guide just mentions 5.2 > 5.2.1 > 5.2.2 > 5.2.3 > 5.3 > 5.4. Its not clear to me.

3) What will be impact on current data on the DMM server. Will it all be able to convert or any special precautions (real world) to be taken.

Thanks & Regards,

Pratik

Hi Pratik,

I am afraid that you have to go step by step from version 5.2 till 5.4

As mentioned by Cisco, for MCS-7835-H3, the supported upgrade path is 5.2 > 5.2.1 > 5.2.2 > 5.2.3 > 5.3 > 5.4.

I know it is painful but in such a way you guarantee a very smooth upgrade.

Make sure to take a backup of all the content, and make sure as well to connect a keyboard, mouse and screen. You will need it during the upgrade process.
