Moving Colo Datacenter

OMatlock — Tue, 18 Sep 2018 16:47:14 GMT

Hi folks,

We got some dreaded news that our colo vendor is not renewing lease and we are now moving.

We have two 3020 firewalls configured in HA.

I am looking for any general comments that could help in my direction.

One thought:

Break HA.
Take secondary firewall over to new colo datacenter.
Edit secondary firewall configuration for new IPs.
Make secondary, new primary.
Bring over original primary, make secondary, sync new config.

Anyone have comments from experience?

Hello,

Once you break HA there is no more Primary/Secondary so I have modified your steps a bit just to be safe.

Shutdown secondary firewall
Disable HA on remaining functioning firewall
Take secondary firewall over to new colo datacenter.
Edit secondary firewall configuration for new IPs
At new Colo, make sure the current running firewall has a lower 'Device Priority' than the one you are brining over
Bring over original primary and cable up
fire up the original primary and make sure to push a config sync from old secondary to old primary

Hope that makes sense.

Good luck!

Thank you @OtakarKlier

I am wondering if there are an suggestions for editing the config?

After I do a rule cleanup, could use find/replace in config file for public IPs?

Sounds scary, but wondering if most config could be populated that way or other, besides only combing through and changing every rule, etc. manually.

Hello,

The config is just an xml file soas long as the formatting is correct, a find/replace should work just fine. I would recommen making a copy or two and just have them, but worst case you have the one in the old colo to refer to.

Obivously once you do the find/replace and boot the device, go through the config to make sure its correct and test it out the best you can.

Cheers!

Thank you @OtakarKlier !!!

Yea, would certainly review and test. Trying to have it in place ahead of time and validate what we can before moving all the servers over. We do all our routing through the PA firewall.

I recently moved my company from an owned DC to a CoLo. I did essentially what you documented except used our "OSS" (On-Site Spare).

The set-up was DC 1 <--> DC 2. I prestaged a third 3020 OSS in the new DC (DC 3). I moved HA to DC 2. Went into the Palo portal and said DC 1's FW was "broken" which transferred the licensing and functionality from DC 1 FW to DC 3's FW.

I then HA peered DC 2 and DC 3's FWs. Once that was squared aware I made DC 3's FW active taking over from DC 2.

The whole process took about 45 minutes never creating an outage and we didn't have to go hours running single threaded.

Thank you! @Brandon_Wertz

Nice to have the OSS.

I wonder if I will be able to transfer the Licensing, etc. to our secondary FW when time comes.

We will have downtime since we will be physically moving our servers, etc. I plan to stand up maybe a test web server and cycle through IPs in the new config to get some level of validation before the servers and switches move in.

Hello,

The licenses should be easy to swap. You could even get your sales team involded, maybe they can give out temp licenses if you need them for a short time.

Cheers!
