Cisco WS-C3750X-24T-S Stack switches Up-gradation From 12.2(55)SE3 to 15.2(4)E6

[raju jadhao]

We have Stack  WS-C3750X-24T-S swiches 1-4 running on 12.2(55)SE3 version.

Due to  recommendation need to upgrade on new version, so we plan to upgrading existing ios to c3750e-universalk9-mz.152-4.E6.bin. 

But new ios size in 25 MB and our flash as below...

#dir flash:1:   57671680 bytes total (23256576 bytes free)

#dir flash1:2: 57671680 bytes total (23300608 bytes free

#dir flash2:3:  57671680 bytes total (7247360 bytes free)

#dir flash3:4: 57671680 bytes total (7247360 bytes free)

I presume the "plan" is to COPY the BIN file to all the stack members? 

[raju jadhao]

hi,
Thank for reply...

But flash memory not sufficient ..?

[Leo Laohoo]

If flash memory is insufficient then delete file(s) that are irrelevant.
I'm keen to know why stack members 3 & 4 have very low free space left.
Care to share what the contents of the flash are?

I see that switch member 3 & 4 have been "upgraded" by copying the BIN file across (instead of the recommended "archive download-sw").

[balaji.bandi]

Delete the Old files and upload new IOS image, make sure while doing this process, do not reboot and reload the devices.

After succesfull of delete and upload - change the boot varialble, use maintenance window and reload the stack, if possible let have console access and physicall some one available. if the stack was not rebooted for while. ( in case unforseen issue arrises).
