## New Feature

# Upgrading from Previous Mitto Versions

## General - Files Not Upgraded

Mitto installs a number of files that may be modified by the user, post-installation.
To avoid overwriting user modifications during subsequent upgrades, the following files
are not updated by `mitto upgrade`:

* `/opt/mitto/etc/nginx/nginx.conf`
* `/opt/mitto/static/login.html`
* `/opt/mitto/static/index.html`

Thus, if a Mitto release contains changes to one or more of these files, those changes
must be manually made after running `mitto upgrade`.

If a release does not contain modifications to the above files, this section can be
safely ignored.

## Mitto 2.8.1 - Files Not Upgraded

The changes for MIT-1789 required modifications to `nginx.conf`.  Because `nginx.conf`
is not automatically updated during an upgrade, it must be manually updated after
running `mitto upgrade`.  Once `nginx.conf` has been updated, `waf` must be restarted.

The following commands will apply the changes to an *unmodified* `nginx.conf`, saving
the original as `nginx.conf.orig`, and restart `waf`:
```sh
$ sudo bash -c "sed -E -i.orig  's/\|v2/\|messages\|v2/' /opt/mitto/etc/nginx/nginx.conf"
$ sudo systemctl restart waf
```

To confirm the changes were made:
```sh
$ diff /opt/mitto/etc/nginx/nginx.conf /opt/mitto/etc/nginx/nginx.conf.orig
<         location ~ ^/api/(about|history|graph|credentials|credential_types|tags|webhooks|webhooks|messages|v2)(/.+)? {
---
>         location ~ ^/api/(about|history|graph|credentials|credential_types|tags|webhooks|v2)(/.+)? {
```
