Hi, We have an OSA installation with 10-12 compute nodes running Mitaka on Ubuntu 16.04. As initially we have not prepared any long term update strategy we would like to create one now. Plan would be to upgrade it to new OSA release(Ocata/Pike/Queens) in near future. Our original plan was to update management/networking/backend at once by using rolling updates to newer release and then upgrade compute nodes one by one to new release.. I think that [2] provides a general upgrade manual. Is there any document describing how are different OSA releases compatible ? Is there any policy in place about backward compatibility ?
