Hi Guys,

i need to know if this type of migration is possible and how i can do it.

beacuse i have to replace a 620 controller with a 7010.

 

have you some suggestions?

 

Best regards

Andrea

Yes it is possible , just keep in mind that is not recommended to use your 7010 as master controller.

Hi,

thanks for you answer.

 

can you explain how i can do it and why is not recommended to use 7010 as master controller?

 

thanks in advacne

Best regards

These controllers are meant to be used at branch offices, so these have limited capabilies compare to a 7200 controller which are built to be Master.

You can either have these setup as Local controller or be a single Master controller but not master to other local controller

Hi,

thanks for your answer.

For the migration:

can i simply export the configuration by 620 to 7010?

Or i have to modify some parameters such as network interface's name?

 

there is some guide?

 

thanks in advance 

Bset regards

 

Hello,

 

How I usually do this: (prepartion in LAB!)

take flash back-up from old controller

restore your flash on the new controller

IMPORTANT: add your licenses to your new controller after restoring the flash-backup, since licenses are in the flash-backup, and you will need to migrate/transfer your licenses to your new controller.

reload new controller

write memory only after the reload.

Now your configuration is identically as your old controller (also the IP so don't let the 2 controllers be active in the network at the same time! ) 

EDIT(yes you need to configure your interfaces afterwards)

 

Other option, which my colleague usually does: make new controller a local controller connected to the 620 (but SW should be the same on the 2 controllers! )

let all APs redirect to the new local controller (new IP, so also change in DNS etc,... that's why I do it like it is described first ) , make the new local controller master, and remove the old master

 

Kind regards,

 

Hi,
can you explain me how i can modify the interfaces?
and if i follow the first way the version of the two controllers have to be the same?

best regards

HI,

Hi Friend,

 

While you are planning to migrate an old controller to a new model you have consider the following points,

 

1. WLAN configurations

2. L2 and L3 configurations

3. Local database

4. License

 

As a good and successful practice,

 

1. take the flash backup from the old controller, use the command " backup flash"

this take care of first 3 requirements.

 

2. boot the new controller and factory rest the controller, use the command " write erase all"

 

3. After rebooting the controller, copy the backup file in to the flash

 

note the file name must be "flashbackup.tar.gz"

4. restore the flash backup, use the command " restore flash "

 

5. Now configure the L2 and L3 interfaces accordingly ( mostly you have to work on mapping interface to the respective VLANs)

 

6. transfer the license.

 

7. reboot the controller.

 

for any reason if the flash is not restored, please repeat the steps 1,3 and 4

 

Hope got some more clarity,

 

Please feel free for any further query on this.

 

Hi,
i have followed your suggestion and all works fine. =)
The only problem was due to the protocol used to transfer the flashbackup.tar.gz file.
with the TFTP the file was corrupted, i have solved with FTP.
I think can be a point to remember.  =)

 

 

 

thanks for all.

 

Kind regards
Andrea

hi

how to import backup on 7010 controller in CLI?

 

thank you

Sorry to bump an old thread, but we are looking at a similar situation.  Our current environment has a 650 controller in the datacenter which is designated as the master.  Then we have a 620 local controller at each of our satellite offices (~60 offices total).

The design has worked really well for us over the years, however it is now time to upgrade.  We were planning to just install a 7010 as the new master controller in the datacenter (replacing the 650), and then also install a 7010 at each satellite office to operate as the local controllers (replacing the 620's).

Can you help me understand why this is not a recommended design?  I'm not opposed to designating a 7210 as the master and using 7010's for the locals.  But if the 7010 would suffice as master, I would prefer to go that route.  My understanding is that the 7010 is the recommended replacement for a 650 (and 7005 replaces 620) so I was hoping that it would meet our needs for the master, and then give us a nice upgrade for the satellite offices as well.

I haven't been able to find anything in the documentation that says why it is not recommended to use a 7010 as the master, however.

 

I appreciate any guidance or knowledge you could pass along on this topic. 

#7010
#7210

The 7000 series are built and tested to be branch controllers. The master controller needs to be larger than the locals in a large environment like this because of the management overhead and processing requirements of a master controller. 

A 7000 can be a master for another single 7000 of the same model, but should not be used as a master controller for multiple local controllers. 


Thanks, 
Tim

Thank you!  I appreciate the quick response and the guidance.
