Replacing MSM: Software incompatible

[craymond]

We replaced an MSM on a BD8810. When we first installed it, It upgraded firmware and then came online. We had though that it had just installed new firmware to the new card and it was working as expected. However, now I have noticed that it actually pushed the updated firmware to the primary (currently unused) partition on the working MSM and now MSM-A and MSM-B have different firmware. The active MSM is using the secondary image at 12.2.2.7 (primary = 12.5.4.5), while the inactive MSM has both images at 12.5.4.5. If the active MSM fails will it now reboot because the images are incompatible?

Hello Craymond

Sync makes the two MSMs exactly the same without having to connect to a TFTP server and uploading and downloading the files to and from the MSMs.

You absolutely can download the code to the other MSM if you like with no issues.

Thanks

Were you able to get everything sorted out with the info here in the thread?
Got both MSMs In Sync and all versions sorted out? Here's an example from one of my lab cores.

Thanks for the info.

The Synchronize command is just designed for this purpose, it syncs the backup MSM with the active MSM to have the same software versions and files (like policy files and so on).
