Trying upgrade from 0.74 to 1 / replica

Description

I want to upgrade a running 0.74 without replica/OpLog deactive to newest version.
I proceed as described here.

echo -e "replication:\n replSetName: “rs01"” | sudo tee -a /etc/mongod.conf
sudo systemctl restart mongod
mongo
> rs.initiate()

and expand the Environment Line to:
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat ROOT_URL=http://xxxxx.yyyyyy.zz:3000/ PORT=3000 MONGO_OPLOG_URL=mongodb://localhost:27017/local?replSet=rs01

the mongo-log shows “MongoError: not master and slaveOk=false”, so I have to enter
rs.slaveOk()
in mongo-shell after every boot. The RC service is starting now, but in the client there’s a message “502 bad gateway”

I’m freshly new to RC and have no idea what to do! Any help?

update:
I got RC1.0.3 running with mongo 3.6.12, but it seems that now I need to start the rocketchat service manually after each server restart.
After restarting rocketchat the message
MongoError: not master and slaveOk=false
is still there, but now the service starts.
