Look for and take note of these directory paths in the amanda.conf file:

logdir "/var/lib/amanda/test"
infofile "/var/lib/amanda/test/curinfo"
indexdir "/var/lib/amanda/test/index"
tapelist "/var/lib/amanda/test/tapelist"

Find out where the amanda home directory is located:

[amanda@vmservercomm test]$ cat /etc/passwd | grep amanda
amanda:x:501:6::/var/lib/amanda:/bin/bash

Make a list of all the amanda directories and files that will be affected on the upgrade:

bindir             /usr/local/bin 
sbindir            /usr/local/sbin                             
libexecdir         /usr/local/libexec                                                  
AMANDA_DBGDIR      /tmp/amanda                           
CONFIG_DIR         /usr/local/etc/amanda                    
listed_incr_dir    /usr/local/var/amanda/gnutar-lists  
logdir             /var/lib/amanda/test
infofile           /var/lib/amanda/test/curinfo
indexdir           /var/lib/amanda/test/index
tapelist           /var/lib/amanda/test/tapelist
tapedev            file:/space/vtapes/test/slots
changerfile        /var/lib/amanda/test/changerfile
holding disk path  /space/amandahold/test

Remove the old user amanda from the passwd and shadow files:

[root@vmservercomm ~]# cat /etc/passwd | grep amanda
amanda:x:501:6::/var/lib/amanda:/bin/bash
[root@vmservercomm ~]# cat /etc/shadow | grep amanda
amanda:!!:13276:0:99999:7:::

Remove the old user amanda from the group disk in /etc/group file:

disk:x:6:root,amanda

Remove the old amanda xinetd files:

[root@vmservercomm ~]# cd /etc/xinetd.d
[root@vmservercomm xinetd.d]# ls | grep amanda
amanda
[root@vmservercomm xinetd.d]# rm amanda
rm: remove regular file `amanda'? y

Create a temporary directory called /amandamove for amanda files to to copied to while upgrading:

mkdir /amandamove

Tar up the files and dirs containing the logs, curinfo, indexdir and tapelist in to the /amandamove directory:

[root@vmservercomm amanda]# pwd
/var/lib/amanda
[root@vmservercomm amanda]# ls
test
[root@vmservercomm amanda]# tar -cvf /amandamove/index_curinfo.tar *

Tar up the files and dirs containing all the amanda config files in to the /amandamove directory:

[root@vmservercomm amanda]# pwd
/usr/local/etc/amanda
[root@vmservercomm amanda]# ls
test
[root@vmservercomm amanda]# tar -cvf /amandamove/amanda_config.tar *
test/
test/disklist
test/amanda.conf

Copy the /var/lib/amanda/.amandahosts to /amandamove:

cp /var/lib/amanda/.amandahosts /amandamove

Remove the old amanda directories:

[root@vmservercomm var]# rm -rf /var/lib/amanda
[root@vmservercomm var]# rm -rf /usr/local/etc/amanda
[root@vmservercomm var]# rm -rf /tmp/amanda

Remove all amanda files from /usr/local/sbinand /usr/local/bin:

[root@vmservercomm sbin]# ls
amadmin    amcleanup  amflush    ammt        amreport   amstatus    amtoc
amcheck    amdd       amgetconf  amoverview  amrestore  amtape      amverify
amcheckdb  amdump     amlabel    amrecover   amrmtape   amtapetype  amverifyrun
[root@vmservercomm sbin]# rm -rf *

Install the amanda enterprise rpm:

[root@vmservercomm server]# rpm -ivh amanda_enterprise-backup_server-2.5.0int9-1.fc4.i386.rpm

Extract the amanda config files from /amandamove in to /etc/amanda:

[root@vmservercomm amandamove]# pwd
/amandamove
[root@vmservercomm amandamove]# cd /etc/amanda
[root@vmservercomm amanda]# tar -vxf /amandamove/amanda_config.tar
test/
test/disklist
test/amanda.conf

Extract the amanda logs, curinfo, indexdir and taplist from /amandamove in to /usr/lib/amanda:

[root@vmservercomm amanda]# cd /var/lib/amanda
[root@vmservercomm amanda]# ls
gnutar-lists  template.d

Copy the .amandahost file from /amandamove to the /var/lib/amanda directory:

[root@vmclientcomm amandamove]# cp /amandamove/.amandahosts /var/lib/amanda/
cp: overwrite `/var/lib/amanda/.amandahosts'? y

Change onwership on the following amanda directories:

[root@vmservercomm amanda]# chown -R amandabackup:disk /var/lib/amanda
[root@vmservercomm amanda]# chown -R amandabackup:disk /etc/amanda
[root@vmservercomm amanda]# chown -R amandabackup:disk /space

Edit the /var/lib/amanda/.amandahosts file and chnage all the amanda user entries to amandabackup

vmredhatclient.zmanda.com root
vmredhatclient.zmanda.com amandabackup

Edit the amanda.conf file in /etc/amanda/test/amanda.conf and change the user entry from amanda to amandabackup:

dumpuser "amandabackup"

Run amcheck on the configuration to see if the upgrade is complete (the error below is expected if you havent upgraded the client yet):
