  • 1.  Distributed Switch Migration

    Posted Sep 25, 2014 01:06 PM

    I am planning a migration away from the Nexus 1k and am trying to do this with zero downtime.  I found a blog post that discussed switch migration and built a project plan around this, but wanted to see if what I was planning seemed workable.  Anyone have any thoughts on the following plan?


    1. Build new VMware Distributed Virtual Switch with all required VM networks
    2. Go into each host and build a local switch with all required VM networks with network names appended with “_local”
    3. On first selected host Detach one of the 10G nics from the 1K and attach to new local switch(expected ping loss is 1 or 0 pings)
    4. Go into each VM on selected host and change VM portgroup to corresponding “_local” portgroup(expected ping loss is 1 or 0 pings)
    5. Detach remaining 10G nic on 1K and attach to local switch
    6. Remove selected host from 1k
    7. Add one 10G nic on selected host to DvS created in step 1(expected ping loss is 1 or 0 pings)
    8. Go into each VM on selected host and change VM “_local” portgroup to corresponding portgroup on DvS(expected ping loss is 1 or 0 pings)
    9. Detach remaining 10G nic on Local switch and attach to DvS
    10. Remove Local Switch
    11. Repeat steps 3-10 for all remaining hosts

    Why use the local switches in between? Can't you simply use the migrate networking option on the VDS to get the VM networking directly to a VDS?

    Correct Girish, that can be migrated directly from vds.
