upgrade multiple vShieldEdges using REST API

Hi all

We plan upgrading our vCloud 5.1 to 5.5.x.

An huge task would be upgrading the ~200 vShield Edges after update the vShieldManager.

In the vShield API dokumentation i found how upgrading to 5.1 using 2.0 API but nothing upgrading to 5.5.x..

In my understanding - after Upgrading vShield manager to 5.5.x there no more 2.0 API, only 3.0.

How can i upgrade the vShield Edges to 5.5.x using an API 3.0 script?

i already have created an filtred using GET https://x.x.x.x/api/3.0/edges

Cheers

Dominik
