Step 1: Backing Up the Source Database Server to ISM

To back up the source database server to ISM

Execute the hostname command on your source and target computers.
Bring the database server to quiescent mode with the following command:
```
onmode -s
```

Set the following ISM environment variables:

UNIX Only

On UNIX:

ISM_SERVER = source_hostname
ISM_DATA_VOLUME_POOL = ISMData
ISM_LOG_VOLUME_POOL = ISMLogs
export ISM_SERVER 
export ISM_DATA_VOLUME_POOL
export ISM_LOG_VOLUME_POOL

End of UNIX Only

Windows Only

On Windows:

set ISM_SERVER = source_hostname
set ISM_DATA_VOLUME_POOL = ISMData
set ISM_LOG_VOLUME_POOL = ISMLogs

End of Windows Only

Perform a full backup of the source database server:
```
onbar -b -L 0
```
Back up copies of the following critical files located in the $INFORMIXDIR/etc (UNIX) or %INFORMIXDIR%\etc (Windows) directory. When you perform an imported restore to another computer system, you will need to restore these files.
Dynamic Server
On Dynamic Server, copy the following files:
```
oncfg_source_dbservername.servernum
ixbar.servernum
# for UNIX users only
$ONCONFIG
sqlhosts 
# for Windows users only
%ONCONFIG%
```
End of Dynamic Server

Windows Only
On Windows, use regedit to copy the sqlhosts information from the source computer to the target computer. Use the following registry entry:
```
HKEY_LOCAL_MACHINE/SOFTWARE/Informix/SQLHOSTS/...
```
End of Windows Only

Extended Parallel Server
On Extended Parallel Server, copy the following files:
```
onconfig.sourcecomputer
Bixbar.hostname.servernum
# for all coserver numbers, copy the oncfg files
oncfg_source_dbservername.servernumber.coservernumber
sqlhosts
xcfg_sourcecomputer.servernumber
```
End of Extended Parallel Server

Complete the following steps to make your security portable to the new computer:

UNIX Only

On UNIX:

ism_add -admin root@target_hostname
ism_add -admin informix@target_hostname

End of UNIX Only

Windows Only

On Windows:

ism_add -admin Administrators@target_hostname
ism_add -admin informix@target_hostname

End of Windows Only

Save the bootstrap of your source ISM server:

UNIX Only

On UNIX:

$INFORMIXDIR/bin/ism_catalog -create_bootstrap \
-pool $ISM_DATA_VOLUME_POOL

End of UNIX Only

Windows Only

On Windows:

cd %INFORMIXDIR%\bin
ism_catalog -create_bootstrap -pool %ISM_DATA_VOLUME_POOL%

End of Windows Only
