Appendix C Upgrading from an Old Product

This appendix describes how to upgrade an environment that was configured based on an earlier version of the Cloud Storage Gateway (hereafter "old product") to the current version of the Cloud Storage Gateway (hereafter, "this product").

The upgradeable versions are as follows:

Table C.1 Old versions that can be upgraded
Upgrade target version	Upgrade availability
V1.0.x (x is 0, 1, 2,...)	OK
Other versions	NG

In addition, the following combinations of operating environments are possible. The operating environments of the old product and this product must be same. However, the virtual hosts where the old product and this product operate can be different as long as they are in the same operating environment.

Table C.2 Combination of operating environment
Operating environment of the old product	Operating environment of this product	Upgrade availability
VMware vSphere	VMware vSphere	OK
	KVM	NG
	Hyper-V	NG
KVM	VMware vSphere	NG
	KVM	OK
	Hyper-V	NG

Note

Deploy this product in the same datastore (VMware vSphere) or file system (KVM) as the old product.
