How to replace core switch

We are looking at changing our SAN core switch and am just wondering if there is a guide out there on how to do this. All our edge switches are connected on trunk port on the core switch. What are the steps to take to accomplish this.

Thanks

Re: How to replace core switch

Hi Adeniyi,

This is a complex task and it depends on many factors. Are you migrating from McData Fabric or is your fabric Brocade in native mode?

What switch type are you decomissioning, what is your new switch. What is your version of FOS in all switches in your SAN (lowest, gratest)

Are you using redundant fabrics?

A good document to start with is the "SAN Migration Guide". General concepts that will help you get started but you should ideally contact your service representative to assist you in this task. This is my recommendation.

Best regards,

Re: How to replace core switch

If your SAN is redundant then you can upgrade by replacing switches, remember to save the switch configuration in advance in three basic steps

configupload -all

physically change the old core switch for the new one

configdownload

You have to check compatibility between your old edge switches and your new core switch.

The only guide (old) in Brocade website is the "SAN migration guide", it can help you anyway. I have attached it.

Alternativly you could merge your new switch in the existing fabric.

Schedule downtime for the switch it should replace and patch your devices on the new switch.

You have to have zoning based on (p)wwn.

nerverdie's method will work with both (p)wwn and did/pid zoning.
