pix 515 upgrade

hi everyone,

i have pix 515E with 64MB RAM , Flash 16MB with Restricted License and PDM installed using version 6.3(4)

I need to upgrade it to version 7, so is it possible that the upgrade will be successfull or would i have to put more RAM before doing an upgrade.

Hi,

I think you may be ok, the advisory on RAM states that for Version 7 you need 64Mb for Restricted. Take a look here

great thanks,

actually there is another question, which i read in the documentation that if i have PDM installed and try to upgrade to 7 with 64MB then it would not be possible and also the procedure of upgrade should be through monitor mode instead of network.

any ideas, suggestions or advice on this.

Sorry not sure on that one. I wont install the PDM unless its absolutley necessary as it provides an additional service that the firewall is doing (increases its attack footprint by adding more services).

The update is quite simple, i am sure there is a Cisco paper on this somewhere (if you need it then let me know and i will find it).

Cheers

thanks smurf,

actually i was trying to get addtional adivce as i will be doing it today. any screw ups can be dangerous.

surly i know the upgrade procedure, has done it in live with number of firewalls but not in with this scenario.

thanks anyways.

I updated our firewalls from version 6.3 to 7 and it was a simple process. Luckily, i had enough space to copy the new version 7 code over and maintain the old version 6.3 so i could easily roll things back if it wasn't happy.

I would suggestion making a backup copy of your config, the upgrade to version 7 will convert the config for you and it should create a backup of the original. I would still make your own backup of the config file. Also, i would check through the upgrade notes because some of the version 6.3 commands have changed (fixup is gone), most of them will be automatically converted to the new syntax but i cannot remember if there was a few others that it didn't do so i would strongly recommend reading the notes.

Fingers crossed for ya fella
