Increasing Public/Private subnet for databricks workspace

Question

Is it actually possible to increase the public/private subnet for an existing databricks workspace ?
I have tried changing the subnet from /26 to /24 and deligated it back to the Databricks workspace, what I have noticed is that I was able to start the cluster and create a new schema, however, I was not able to create a table and insert records into the table.

Can Microsoft help in changing the subnet range?

Hello @veerabhadra reddy kovvuri ,
Thanks for the question and using MS Q&A platform.
I don't think its possible . As you may already be aware that ADB has got two plane on is the management plane and the other is data plane . I guess the changes which you made went through the management plane and so you are able to start the cluster but its didnr worked for data plane .
You can explore the option to move to a new workspace .
