How to upgrade N3K-3064-TQ when not possible to free space on bootflash?

[Tibor M]

Hi,

we are running Nexus 3064-T switch on 7.0(3)I5.1 image... we would like to upgrade to 7.0(3)I6.2 but we have following problem.

Bootflash has just 1650905088 bytes size. Current image size is 757450240 bytes and new image is 798377984 bytes but on flash is just 795848704 bytes free.

so including current image and "something" on bootflash is used 855056384 bytes. So totally no space to upgrade. I do not know where are hiding 97606144 bytes of "something".

So how to proceed with upgrade in this case? boot through serial cabel, format flash, recover image from network/usb and restore config?

Thanks
