QuTS hero 5.3.1

Hello,

I’m using TBS-h574TX.
it looks there is 5.3.1.3250 on the download site. But my 574TX doesn’t recognize that firmware by onlineupdate.

Her eis my question.
Is it reasonable to understand as 5.3.1 is a public stable version? is there any reason I can’t apply it via online update?

I AM interested in to use immutable snapshot. So if there is no issue to use 5.3.1, I would like to update my one to there.
it would be great if I could get any advice!

Thank you!

Hi there, what firmware version are you currently on for your TBS-h574TX?

Please note there are some important considerations for updating to the 5.3 series. If you’re coming from the 5.2 series, you’ll need to download the update file from our official website and perform a manual update. Make sure you read our release notes before you begin.

Once you’ve successfully updated to the 5.3 series, all subsequent 5.3 versions can be installed via online updates.
