Low VXRM storage warning and vxrail update

Hello,

i am planning to upgrade vxrail to latest update package . the precheck shows a Warning that vxrm /root is low in space at 35%. can i still upgrade or i have to free up some space just in case on the vxrm ?

i found that there is a log bundle package created in the tmp folder in vxrm . its about 3gb not sure if it is safe to delete or not manually.
