I developed a plugin using vsphere web client sdk 5.5 and did required changes to make it compatible with wc 6.0 as mentioned in below link:
2 Important reminders for your 5.5 plugin to be compatible with Web Client 6.0
Plugin works fine on both 5.5 & 6.0 versions.
As per docs, web client 6.0 is compatible with vCenter servers version 5.5. So, I started using web client sdk 6.0 for plugin development and it also works fine on vCenter 5.5 & 6.0. Didn't test it on 5.1 yet.
But, my requirement is to make plugin work on all vsphere versions 6.0, 5.5, 5.1 or prior to 5.1.
Is plugin developed with sdk 6.0 will work on prior to 5.5 releases ?
