RPM package upgrade from 1.11.8 -> 1.12.2 fails and removes systemd unit file

[devanbenz]

Steps to reproduce:
List the minimal actions needed to reproduce the behaviour.

1. download influxdb 1.11.8 and 1.12.2 rpm packages from https://repos.influxdata.com/packages/
2. Install version 1.11.8 of influxDB on your choice of RHEL system (i.e. Rocky, CentOS, RHEL) yum localinstall <influxdb1.11.8>.rpm
3. Run systemctl enable --now influxdb
4. Verify influxdb is running systemctl status influxdb
5. Upgrade to version 1.12.2 using yum localinstall <influxdb1.12.2>.rpm
6. Run systemctl daemon-reload
7. Run systemctl status influxdb and see an error that there is no unit file

Expected behaviour:
InfluxDB upgrades from 1.11.8 to 1.12.2 successfully.

Actual behaviour:
During the upgrade process we see the following:

# yum install influxdb-1.11.8
...
# yum upgrade
...
(9/10): influxdb-1.12.2-1.x86_64.rpm

Failed to enable unit: Unit file influxdb.service does not exist.

If you take a look at the 1.11.8 vs 1.12.2 post install files you'll notice that we use sysV previously where we are now using systemd. This is currently where I hypothesize the issue stems from.

Same problem here.

Force a reinstall on my side solve the issue:

sudo dnf reinstall influxdb-1.12.2
