When upgrading one or more colonies using
the colony-by-colony upgrade strategy, you must first create an upgrade
environment, by performing the following tasks, as shown in Figure 1:
Procedure
Install an upgrade environment in the version
that corresponds to the current version of the sharded deployment.
In this example, install a new Release 9.4. run time in sharded mode
(Upgrade_V1).
For each colony in Production_V1 that you
are upgrading, add a new colony to Upgrade_V1. The new colony acts
as a placeholder in Upgrade_V1 for the colonies in Production_V1 that
you are upgrading. Later, you will move the colonies from Production_V1
to Upgrade_V1 and replace the placeholder colonies. In this example,
add CLY1_new to Upgrade_V1.
Note: The DEFAULT
colony is included with all new sharded installations.
