I'm planning on doing an upgrade of my 3850 stack and just don't have the space when doing the installation(expansion of flash to install file)
The current version I'm on is 3.6.4 and if I remove the 3.6.4 bin file from flash, I'll have enough space to upgrade to 16.3.7. Is it ok if I remove that file?

As you can see line item #2 is the bin file for installing the old version 3.6.4. Is it ok if I delete that so I can install 16.3.7? I'm scared because I don't want to break the stack before doing the software upgrade to 16.3.7. I can't seem to find any documentation on the software release notes to mention if you can delete the bin file of the current software version that your stack is running.
