What do i do next

I have a Pi3B with PiAware (SD Card) 7.1 and have made changes such as
storing ADSB and MLAT Data on csv/sql databases locally on an attached HDD.
writing self healing programs that analyze and correct problems
and other additions that don't change the location of standard software.

My question is how do I upgrade to wiedehopf's software (1090) without ruining what I have developed/ changed in the past

Thanks

 

I occasionally have dhcpcd problems so installed the folllowing setting dhcpcd as a service

Code:

sudo mkdir -p /etc/systemd/system/dhcpcd.service.d
sudo tee /etc/systemd/system/dhcpcd.service.d/restart.conf <<"EOF"
[Service]
Restart=always
RestartSec=5s
StartLimitInterval=1
StartLimitBurst=100
EOF
sudo systemctl daemon-reload
sudo systemctl restart dhcpcd

But I seem to have overlapping coding

Code:

-- A start job for unit dhcpcd.service has begun execution.
--
-- The job identifier is 13510.
Jun 25 17:17:02 piaware dhcpcd[6457]: Not running dhcpcd because /etc/network/interfaces

This is the prog mentioned:

Have you any suggestions? TIA
