Upgrade story beyond Stratos 4.1?

["Shaheedur Haque (shahhaqu)" <sh...@cisco.com>]

Hi all,

Once 4.1 is deployed, do we know what the upgrade story will be to the next release beyond that? Specifically:


*        My assumption is that running Cartridges will not need to be touched

*        I'm not sure what a possible upgrade procedure would be (note: we will have either 2 or 3 servers able to run Stratos configured as a pacemaker cluster)

If this is this documented somewhere, I'd appreciate a pointer please.

Thanks, Shaheed

Hi Shaheed,

The easiest approach would be to migrate all the artifacts deployed in the
existing environment (Stratos 4.1.0) to the next Stratos version (X) and
deploy them in a fresh Stratos X environment. Then switch the incoming
traffic from the older environment to the new. Later stop the older
environment if there are no issues with the new.

Currently it is difficult to migrate Stratos data as they are stored in
binary format in the registry database. Jane is now working on a task to
fix this by introducing database tables for each component.

Still there could be situations where live migrations might not be possible
within the same environment depending on the complexity of the changes we
do in a release.

Thanks
