SAP Note 25022 - Moving the Upgrade directory WINDOWS NT

Symptom:

Disk space under the Share SAPMNT is not sufficient for upgrading

Cause and prerequisites
Solution
Move the upgrade directory :
- Create a directory \USR\SAP\PUT on a disk drive with sufficient
free space
- Maintain the parameter DIR_PUT in your instance-specific profile
e.g. DIR_PUT=E:\usr\sap\put
- Restart your system
- Import the data for the Release upgrade into this directory and
start R3up from this newly created directory tree.

Additional key words

Please note:
UPGRADE DIRECTORY
If you create Ihr Upgrade directory \USR\SAP\PUT on another
disk drive as \\$(SAPGLOBALHOST)\SAPMNT\put, you must
maintain the profile parameter DIR_PUT.
After making the change in profile, restart your system.
TRANSPORT DIRECTORY
The transport directory can generally be moved under WINDOWS NT as
described in Note 13352.
However, a temporary transport directory \USR\SAP\TRANS is always
expected under the path \\$(SAPGLOBALHOST)\SAPMNT\TRANS for the
upgrade up to R/3 3.0D, under which any transport requests during
the upgrade can be stored.
