800xA MSI upgrade
Hi!
Would like to know if it is a "big bang scenario" of upgrading system 800xA (to ver 6.0.x from 5.1FP4) with an MSI on top (subscriber and provider at the same time) or if it is possible to wait with the provider systems?

Hello,
To get all the benefits the new version 6.0.x have the best way is to install a totally new system, then make a new 800xA project and import all components from the "old" system manually and in the correct order.
It is also possible to reduce the number of nodes in version 6.0 duo to much better usage of hardware then older versions, theirfor it is also better to make the upgrade manually though export/import to place 800xA services smarter.
Their is a totally new way of configuring nodes and services in version 6.0 and to get this working with restoring a backup is to complicated.
To get minimal downtime the best way is to run version 5.1 and version 6.0.x in parallel. It is also a very good solution to verify that the new system works the same way as the older before shutting it down.
