IF YOU UPDATE AN ADM PLATTFORM FOR FUCKS SAKE DON'T DO THE FOLLOWING THINGS:

1. ONLY DOCUMENTATE IT IN A POWERPOINT

2. WRITE DOWN IPs AND PORTS ONLY ON A WHITE-BORD

3. MOVE TOOLS TO OTHER SUBNETS OR DOMAINS WITHOUT PROPERLY KNOWING THE WAYS OF COMMUNICATION BETWEEN THEM

4. USE YOUR PERSONAL EMAIL ADDRESS AS RESET OPTION FOR LICENCE-MANAGEMENT ACCESS IF NO ONE KNOWS THE PW

5. LEAVE THE COMPANY THE DAY AFTER THE UPGRADE IS DONE

Because the guy who has to take care of the upcoming problems is not going to like you!

BUT having to deal with all of this at once would not be a problem if your, so called team (30 People who work with those applications e.g. as test-engineers) would actually work together instead of having that "not my daily business, I am going to drink coffee" attitude.

Apparently I am the only one who has enough balls to see, admit, and report a problem to our leadership.
This always leads to Me fixing the issue...
....that's alright I am learning a lot...
...BUT IF A TEAM-MATE, WHO HAS THE SAME DEGREE AS I AM GOING TO GET, LEAVES EARY BECAUSE: "HE DOES NOT KNOW WHATS WRONG", IT TRIGGERS ME!!!

PS Needless to say hundreds of clients have access to those systems and I worked through a shittload of official tool docs just to get to know the tools first...
