2. Check if all the processes are running from the new upgraded GRID HOME and no process belongs to the OLD GRID HOMES

3. Number of old grid homes that needs to be removed

[root@testlinux ~]# cd /u01/app/
[root@testlinux app]# ls
19.0.0.0 19.14.0.0 19.18.0.0 19.20.0.0 grid odaorabase odaorabase0 odaorahome oracle oraInventory

4. Go to the GRID HOME that needs to be removed

[root@testlinux app]# cd 19.0.0.0/
[root@testlinux 19.0.0.0]# ls
grid
[root@testlinux 19.0.0.0]# cd grid/

5. Give full GRID owner rights to the GRID HOME as it also contains files that belongs to “root”
[root@testlinux grid]# chown -R grid:oinstall /u01/app/19.0.0.0/grid/
[root@testlinux grid]# chmod -R 775 /u01/app/19.0.0.0/grid/

6. Switch to the GRID User

[root@testlinux grid]# su – grid
Last login: Mon Mar 18 10:29:55 +04 2024
[grid@testlinux ~]$ env | grep ORACLE
ORACLE_SID=+ASM1
ORACLE_BASE=/u01/app/grid
ORACLE_HOME=/u01/app/19.20.0.0/grid

7. Go to desinstall folder and dry run the deinstall command

[grid@testlinux ~]$ export ORACLE_HOME=/u01/app/19.0.0.0/grid
[grid@testlinux ~]$ cd $ORACLE_HOME
[grid@testlinux grid]$ pwd
/u01/app/19.0.0.0/grid
[grid@testlinux grid]$ cd deinstall/
[grid@testlinux deinstall]$ ./deinstall -checkonly

For complete clean up of Oracle Clusterware software from the system, deinstall the following old clusterware home(s). Refer to Clusterware Install guide of respective old release for details.
/u01/app/19.14.0.0/grid on nodes : testlinux
/u01/app/19.18.0.0/grid on nodes : testlinux
Review the permissions and contents of ‘/u01/app/grid’ on nodes(s) ‘testlinux’.
If there are no Oracle home(s) associated with ‘/u01/app/grid’, manually delete ‘/u01/app/grid’ and its contents.
Oracle deinstall tool successfully cleaned up temporary directories.
