Hi Cindy !
Thanks for your reply.
Step by step :
a) Start Toad DP 4.2.1
b) Open file ... comparison_saved_from_3.6.1.dcp
c) pop-up : Objects will now be loaded. Do you want to start comparing immediately ?
d) click "YES" button or "NO" button seem to have same effect/behaviour
e) pop-up : LDAP authentication failed for user "me"
f) click OK
g) dialog : Change Comparison Wizzard
h) select valid / different Target server name (from drop down list of defined connections)
i) click "Next >" button
j) ... "extracting schema objects" ... (works for a few minutes)
k) empty dialog "0 of 0 objects will be compared."
When I get to H), the target server name maps to an non-existant connection ( i have to choose a valid one)... Could that be related to my issue ?
Thanks !
