  • 1.  Migration to C35

    Posted 07-27-2017 16:58

    I have a general question regarding migrating from two C25's to two C35's.

    Is there an FAQ or document that can assist in this migration? I seached the GTAK kb without any success.

    Related, I am also about to upgrade my NetSight server ( to Extreme Management Center (8.x).

    I believe I need to upgrade the NetSight (at least or higher) and NAC before the wireless controllers. We do use Policy Manager and Oneview not Purview.

    Would love some advice on the best migration path.

    What version is running on the C25 pair?

    Currently I have running on both C25's, I have 100 AP's (50 on each) and once I've migrated I'll be adding at least 20 more AP's total.

    Hi Stephen,

    sounds good, so install the same version on the C35 and export/import the configuration as mentioned by Craig.

    Have you checked the release notes for EMC v8 for the higher CPU/RAM/HDD requirements ?

    I'd upgrade to EMC v8 before replacing the controller pair - I'd leave it running for some time to see whether everything is working fine before you replace the controller pair.

    Hi Stephen,

    Just add the reference for upgrading EMC v8.

    Considerations for upgrading Extreme Management Center to version 8.x (formerly Netsight)

    Best regards,

    If you have access to the software manuals you should look at the section..."Migrating the Platform Configurations" in the ExtremeWireless Maintenance Guide. There are sequential steps for migrating a configuration.

    Just talking out loud here...

    I noticed that I'm a few (several) software rev's behind. I think it might be asking for trouble if I were to upgrade the C25's just for the sake of being current before migrating to the new C35's. With all the changes going on my inclination is to migrate at the current version after the NetSight upgrades, and let things run smoothly for a bit. There's no pressing need that I'm aware of at this point where the wouldn't be sufficient. Our new AP's are supported by that software. (Unless the migrating configurations documents recommend it of course.)

    We're an educational institution, so I need to be done by the end of August. Our next "break" is december so I'm thinking hold off on the C35 software upgrades till then if needed.

    Thanks for the info,

    I've been mulling this over, while I would love to time is short for me.

    It seems that the NetSight does support the C35's, so I may need to migrate to the new C35's then work on the Netsight upgrades over the semester.

    The most pressing need is to install new AP's before school starts. That means the C35's have to be done sooner and if I can avoid the NetSight upgrades then it might be the easiest path.

    Release notes for NetSight indicate at least to me that they support the C35 controllers.

    The only thing that comes to my mind where the model of the controller has any impact on the EMC/Netsight version is if you use the Wireless Manager Tool.

    For anything else it shouldn't make any difference.

    Honestly, I'm not 100% sure if we even do use that...

    Thanks! Hardware wise we just got a new server, 16 cores, 64gb, 600gb disks, little light on the disks but we are considered a "small" - "medium" size based on that list so I think we're good.
