Upgrading from AS/U Version A.*.*

This section describes how to upgrade Advanced Server/9000, version A.*.* to version B.*.*.

One of the features of this version of Advanced Server is Windows NT-style printing. This feature means that you can manage Advanced Server print operations in the same way as Windows NT. Advanced Server computers can store print drivers for Windows NT and Windows 95 client computers. Print drivers are downloaded from server to client automatically; client computer users no longer need to load drivers locally.

However, in order to download print drivers on Windows NT client computers, an administrator must associate each printer share with the appropriate print driver(s). Until print drivers are assigned to every print share used by Windows NT client computers, Windows NT clients without these printers already configured will be unable to print. (Other Microsoft network clients are not affected and will continue to print normally.)

If you are upgrading printer shares, you will be prompted during the upgrade procedure to choose whether to enable Windows NT-style printing. If you have a considerable number of Windows NT clients, you may want to postpone enabling Windows NT-style printing until after the system upgrade is complete.

Upgrading Advanced Server occurs automatically when you install Advanced Server, version B.*.* from A.*.*. The asu_inst installation script upgrades all of the saved data items and files from the previous Advanced Server installation. This includes groups, users, and access control lists.

To upgrade Advanced Server

Log on to the UNIX system as root.
NOTE: Before you upgrade Advanced Server, it is strongly recommended that you back up the contents of the /var/opt/asu/lanman and /etc/opt/asu/lanman directories before you remove Advanced Server.
Remove Advanced Server as described in this chapter in "Re-Installing or Removing the Advanced Server/9000." Be sure to save any data and configuration files that you may want to re-use because the AS/U B.*.* upgrade will modify some of these files in a manner that will prohibit their use if you decide to revert to AS/U version A.*.*.
Perform swinstall procedure as described in "Installing AS/U Software."
Type the following command and press ENTER:
asu_inst

This request script will prompt you for information necessary to install and configure your Advanced Server/9000.

The following message appears:

Configuration files from a previous installation of LAN 
Manager for UNIX or AS/U are 
present on this computer. This installation can either 
upgrade or delete these files.

Do you want to upgrade these files [y/n]?

Type y and press ENTER.




	WARNING! If you type n, all previously-saved Advanced Server files will be deleted, including the user accounts database, access control lists, and the lanman.ini file.

The system displays the following message:

Advanced Server has upgraded your printer shares 
successfully.

One of the new features in this release is 'Windows NT-style 
Printing.' Among other things, 'Windows NT-style Printing' 
gives you the ability to store print drivers for Windows 95 
and Windows NT client computers on the server.  Print drivers 
are downloaded automatically from the server to Windows 95 
and Windows NT client computers.  These clients then can use 
the server's printers without loading drivers manually.

However, 'Windows NT-style Printing' requires that the 
administrator update each printer share with the appropriate 
print driver(s) before Windows NT and Windows 95 client computers will be able to automatically download the driver for use of a given printer.

Do you want to disable Windows NT-style Printing y/n? [y]

Type y or n and press ENTER.
- If you choose to disable Windows NT-style printing (y), you will have the opportunity to enable it at any time in the future and your Windows NT clients can continue to print normally.
  To enable Windows NT-style printing after a system upgrade, set the value of the DisableUpLevelPrinting key to 0 in the Advanced Server Registry. Restart the server, and then associate a print driver with each printer share used by Windows NT clients.
- If you allow Windows NT-style printing to be enabled at this time (n), your Windows NT client computers will not be able to print until you associate print drivers with the printer shares used by these client computers.
  For more information about Windows NT-style printing, see the Advanced Server Concepts and Planning Guide.
When you see the following message, upgrade of the server is complete:
The Advanced Server for UNIX Systems is now operational.




	NOTE: As a result of upgrading Advanced Server, most of the values in your previous lanman.ini configuration file are mapped to Advanced Server Registry keywords. Some lanman.ini file parameters are not incorporated into the registry and instead are stored in a new lanman.ini file. A copy of your previous lanman.ini file is saved and renamed lanman.old. For more information about the Advanced Server Registry and the lanman.ini file, see Appendixes A and B.
