Bench deleted bymistake

Hi folks,
I had deleted my bench (name it as B1) by mistake after something went wrong during bench B1 update.
There were 2 sites created using the deleted bench B1.

Now, I installed new bench (name it as B2)and trying to run the 2 instances which was installed using bench B1.

It is not working.
Installing 2 instances on bench B2 will again take almost 3 hours.
Any workarounds, when i delete my bench (not purposefully. :slight_smile: )

Thanks in advance!!!

PS: Never delete your bench as per my observations.
