Workaround/Solution
However, there are some
downsides:
• If step 1 is not followed
correctly, any changes not fully
replicated are lost.
• During steps 2 and 3, any data
written to the original source
container may be lost.
• During step 4, if the data is
not fully replicated back before
the switch is made, it may be
lost.
Alternatively:
1
Create new container on
target DR4000.
2
Set up replication from this
container back to source
DR4000 container.
3
Set up a new disk storage
unit in DMA and make sure
that the DMA is aware of
new images.
4
Import old images back
into the DMA from target
DR4000 (the original
source location).
5
Use new disk storage unit in
DMA and restore data back
to the original client.
