Migration from 5500/7507 to 6509

Thanks for the suggestion,

Since this is the first 6509 with msfc/layer3 switching (In fact we are
still waiting for the box to be delivered) in our network, i am bit worried
if I am planning it right.

Do you think this plan will work?
- Configure 6509 with all VLANs,VTP and trunking similar to the current
setup in offline.
- Make sure it is the vtp server with the higher configuration revision than
the vtp clients(rest 7 switches)
- Connect 6509 to the 5500 switches one by one, make sure the vlan
information(in fact should be the same) flows from 6509 to 5500
(Clarification: this shouldn't delete the currently configured port
assigned to the respective vlans in 5500..correct?)
- Once the vlans are stable, I can create the etherchannels.
- Then I can configure the msfcs with the "interface vlan" commands and
which should enable routing automatically between the vlans.

Few points to take note:
-------------------------
To lower the configuration revision of my 7 switches do "set vtp domain
dummyname" and then "set vtp domain originalname" and this should lower the
configuration revision of the 7 vtp client switches to zero.
If two switches configuration revision are the same(zero), then do some
changes in the vlan database of the 6509 to increment the configuration
revision.

Backup Plan: (Put back 5500/7507 to replace 6509, in case I have to revert
back)
-------------
- Remove the 6509 from the network.
- Connect the master 5500 and 7507 as it is working now using fastethernet
channel and ISL
- Make sure this master 5500 is the vtp server with higher configuration
revision than vtp clients
- Connect into the switches one by one, make sure the vlan information flows
from this master 5500 to other 5500
- Configure the etherchannels back again.

Does it sound okay? Please comment.

Hi,

I assume you are going to go for Hybrid mode setup (catos and supervisor
image) on your new 6500 (what a shame!), if so I would start with the switch
part (catos) and configure it as you would add a 5500, BUT you go for vtp
transparent, this way you don't risk any VLAN corruption, then configure all
your vlans and trunk, as soon as you have connectivity to your 7500, I would
configure the routing engine of the 6500 and create SVI to correspond with
your 7500 vlans and then I would change some ip addresses and run HSRP
between 7500 and 6500 active to be your new 6500 ( I would do this because
you never know if you get the right IOS on your 6500, or you might have
other issues, BUGS and ....) once you are sure the 6500 is doing the job I
would start step by step removing the 7500 and 5500.

If you are having WAN links VPN plan complicated stuff, firewall on the 6500
or IDS and ... Then I would consider running your 6500 in NATIVE mode, I
personally would never run my 6500 in hybrid mode it's waste of resources!

Good luck,

Reza

If you need any spares, like memories, power supplies or second sup engine I
have some that I don't need.
