How to Manually Remove an Old Grid Home After Upgrading/Patching to a Higher Grid Home on ODA

Step 1: Verify the size of the Grid homes

[root@ app]# du -sh *
13G 19.16.0.0 — Old Grid Infra
12G 19.18.0.0 — Current Grid Infra
12G grid
0 odaorabase
4.7G odaorabase0
44G odaorahome
118M oraInventory

Step 2: Take backup of Grid home

cd /u01/app

cp -RP 19.16.0.0 /u05/app/oracle/1916_grid_backup/

[root@ app]# cd /u05/app/oracle/1916_grid_backup/

Step 3: deinstall -checkonly

[root@ app]# ls -ld 19.16.0.0/
drwxr-xr-x 3 root oinstall 4096 Dec 7 2022 19.16.0.0/
[root@ app]# chown -R grid:oinstall 19.16.0.0/
[root@ app]# ls -ld 19.16.0.0/
drwxr-xr-x 3 grid oinstall 4096 Dec 7 2022 19.16.0.0/
[root@ app]# chmod -R 775 19.16.0.0/
[root@ app]# ls -ld 19.16.0.0/
drwxrwxr-x 3 grid oinstall 4096 Dec 7 2022 19.16.0.0/
[root@ app]#deinstall -checkonlyConnect as grid[root@ app]# sudo su – grid
