You can issue the MOVE command to change a TYPE(USER) to TYPE(LSCA):
TSS MOVE(acid) TYPE(LSCA)
NOTE: You need to use the MSCA acid to issue this command.
Then you will need to manually administer the SCOPE, ZONES, and ADMINISTRATION AUTHORITIES
using the TSS ADMIN(xxxx) command.
The password, expiration date and the User Name will all stay the same for the id.
