Post-installation is always necessary when you start working on a newly installed DevEnv host.
After an upgrade of the DevEnv on an existing host, post-install may be necessary, too. In these cases, the Release Notes of the DevEnv version will inform you so.
**Preparation**
**Note on DevEnv versions before 3.6 **
| On older DevEnv versions, you need to download the post-install first. On DevEnv 3.4, first execute this command (as root): `yum -y install elt-ciisrv-postinstall`. On DevEnv 3.5, execute this command (as root): `yum -y update elt-ciisrv-postinstall`
On DevEnv 3.4, first execute this command (as root)
```
yum -y install elt-ciisrv-postinstall
```
On DevEnv 3.5, if you are outside ESO, execute this command (as root)
```
yum -y update elt-ciisrv-postinstall
```
On DevEnv 3.5 inside ESO, and DevEnv 3.6+, there is nothing to do.
**Postinstall**
Afterwards, execute this command (as root):
To run post-install, execute this command (as root):
```
```
# /elt/ciisrv/postinstall/cii-postinstall <choose a role>
# /elt/ciisrv/postinstall/cii-postinstall <choose a role>
