We can not find T2SL64 board in list when we use link capacity upgrade wizard in U2000 V100R002C01SPC003 to make upgrade from N3SL16 to T2SL64, check attached snap shoot. T2SL64 is not in the list.
R&D tried this kind of upgrade in the lab and confirmed that N3SL16 can not be upgraded directly to T2SL64, first replace N3SL16 with N1SL16 then upgrade to T2SL64
1- Change the logical board for N3SL16 to be N1SL16.
2- Use link capacity upgrade wizard to upgrade N1SL16 to T2SL64.
1.Check weather Slot 3 is valid solt for T2SL64 and find it is valid.
2.Use below navigator command to check weather N3SL16 can be upgraded to T2SL64 and we find that T2SL64 is not included in the output list.
