AsyncOS 7.5.1 upgrade

Unanswered Question

We have these new OS releases available:-

     AsyncOS 7.5.1 build 102, 2012-01-31

     AsyncOS 7.5.1 build 028, 2011-11-08


1)     Can we upgrade direct to AsyncOS 7.5.1 build 102..., 2012-01-31?

2)     If something goes wrong can we revert to our current OS which is AsyncOS 7.1.5?

Best Regards,

I would not upgrade to until 7.6 comes out unless you have a need to.  We installed the 7.5.1-028 upgrade and it "broke" one of our filters.  It was flagged MS office attached as a compressed, zipped and placing them in quarantine.  It gets fixed in 7.6 but it's not available for General Release.

Thanks Doug and Jamie for responding to this thread.

Looks like there is no way of reverting to the old OS if things break.

But good to know 7.5.1-102 works so far...

Hello Ruven,

reverting to 7.1.5 won't be a problem, however makes sure you save your configuration with unmasked passwords before the upgrade, as revertion will reset most of your settings.

Also, you can upgrade to any version displayed directly.

Hi Andreas,

Thank you very much for your reply.

Now I am interested to know the steps or commands required to ‘revert to previous version of OS’.

Looking forward to hear from you soon.
