At the end of a current migration and controller upgrade project I'll have some spare FAS2240-2 arrays (with disks) and a spare DS4246 hybrid shelf.  I'll also have a pile of FAS255X controllers.  Is there any reason that I can't just swap the FAS2240 controller modules for the FAS255X modules and install CDOT on the zeroed disks?  What about swapping the IOM6's from the DS4246 and making a FAS2554?

All this kit is under support and fully licensed but I'm not too concerned about long-term support.  I just want to make use of this gear to run CDOT 9.x in a dev/test lab.

Thanks

Steve
