Recover users/groups/passwords after an upgrade

Question

I've just upgraded WL 6.1 sp 2 to WL 6.2 sp 4. To upgrade, I uninstalled WL first,
then installed the new version in the same directory (I have copies of all the
old files). I copied fileRealm.properties and SerializeSystemIni.dat files from
the old installation into the new. When I try to start WebLogic, the error I get
is :
"Exception raised:
COM.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad
byte.
at COM.rsa.jsafe.JA_PKCS5Padding.performUnpadding JA_PKCS5Padding.java)
at COM.rsa.jsafe.JG_BlockCipher.decryptFinal(JG_BlockCipher.java)..."
How can I recover my users/groups/passwords from the old installation?

Answer 1

Just as I expected. Before following my instructions, you might need to change your folder options to show hidden files. Now go to:
'''C:/windows.old/Documents and Settings/<username on XP>/Application Data'''
And copy everything inside the '''Mozilla''' folder to
'''C:/Users/<username on Vista>/AppData/Roaming/Mozilla'''
If the '''Mozilla''' folder doesn't exist, create one.
Now, go to '''C:/windows.old/Documents and Settings/<username on XP>/Local Settings/Application Data'''
And copy everything inside the '''Mozilla''' folder into
'''C:/Users/<username on Vista>/AppData/Local/Mozilla'''
Again, if the '''Mozilla''' folder doesn't exist, create one and rename it to '''Mozilla'''.
Hope this helps!
