First, “bcp OUT” syslogins from your ASE v12.5 dataserver:
bcp tempdb..syslogins out master.v125.syslogins.bcp -c -t"|" -r"\n" -Usa -SSYBPARFRDEV02_DS
Then, connect to your ASE v15 dataserver and create in tempdb a table based on the v12.5 syslogins table (you can reverse the syslogins ddl from Sybase Central or from DDLgen tool):
isql -Usa -SSYBPARFRDEV01_DS -w1000
create table tempdb..ase125logins ( suid int not null, status smallint not null, accdate datetime not null, totcpu int not null, totio int not null, spacelimit int not null, timelimit int not null, resultlimit int not null, dbname sysname(30) null, name sysname(30) not null, password varbinary(30) null, language varchar(30) null, pwdate datetime null, audflags int null, fullname varchar(30) null, srvname varchar(30) null, logincount smallint null, procid int null ) lock allpages on 'default' go
Now you can “bcp IN” the v12.5 syslogins table into the ASE v15 dataserver:
bcp tempdb..ase125logins in master.v125.syslogins.bcp -c -t"|" -r"\n" -Usa -SSYBPARFRDEV01_DS
What’s next ? Connect to the ASE v15 dataserver, and insert the logins from the v12.5 syslogins table into the ASE v15 master..syslogins table. To avoid insert failures because of duplicate logins id, I exclude here the logins ’sa’,'probe’ and ‘guest’:
isql -Usa -SSYBPARFRDEV01_DS -w1000
sp_configure 'allow updates',1
go
insert master..syslogins
select *,null,null,null,null,null
from tempdb..ase125logins
where name not in ('sa','probe','guest')
go
sp_configure 'allow updates',0
go
Character Set convertion issue:
Before to bcp syslogins, consider each dataserver’s character set. If character set are different between dataservers, you’ll need to modify your bcp commands accordingly. Let’s imagine this particular case: SYBPARFRDEV02_DS is roman8 and SYBPARFRDEV01_DS is utf8.
“bcp OUT” then would be:
bcp tempdb..syslogins out master.v125.syslogins.bcp -c -t"|" -r"\n" -Jroman8 -Usa -SSYBPARFRDEV02_DS
“bcp IN” then would be:
bcp tempdb..ase125logins in master.v125.syslogins.bcp -c -t"|" -r"\n" -Jroman8 -Y -Usa -SSYBPARFRDEV01_DS
Option -Y specifies character-set conversion is disabled in the server, and is instead performed by bcp on the client side when using “bcp IN”.
Cross-platform issue:
Your syslogins is coming from a ASE dataserver prior to version 15.0.2 ? Then end-user passwords may not work anymore after a cross-platform bcp. Actually the hash value stored in syslogins..password column is computed natively inside ASE, regarding the byte ordering of the platform (little/big endian). So, depending of platform endianess, you may have to reset all logins passwords. Your syslogins comes from ASE 15.0.2 or above ? Then you should not have this problem. Indeed the hash value stored in syslogins..password column is no longer implemented natively inside ASE. As of ASE 15.0.2, password hash value generation has been improved and is now platform-independent thanks to 3rd-party cryptographic libraries standing outside the ASE executable.
