Hi,
I 'm upgarding my EHP6 ECC6 on NW7.31 and kernel 7.20EXT to EHP7 with NW7.4 and kernel 7.42 U.
i have the error below during KERNEl SWITCH:

1EETQ204 Upgrade phase "KX_SWITCH" aborted with severe errors ("20150130131230")
I check all soft link before start this phase:
dbg -> uc/hpia64
jvm -> /sapmnt/DM1/exe/jvm
nuc -> /sapmnt/DM1/exe/nuc
run -> dbg
uc -> /sapmnt/DM1/exe/uc
but after the execution of the phase, SUM create another link and stop on error:
dbg -> exe/uc/hpia64
exe -> dbg
exe.old
gen
global -> /sapmnt/DM1/global
profile -> /sapmnt/DM1/profile

I need your help to finish this upgrade.
