[SHARE]How you can Update Without Losing Your Data

[Maker]

I will try to make here a guide how to upgrade without loosing any data like chars items, skills etc.

If it's not useful and someone knows a better way, feel free to correct, it will be for the good of the entire community, I think...

 

1. Make sure you have a working database of your new rev installed on MySQL (preferable a separate PC / laptop)

2. Work all of your new rev files just like being a full new release and you had none before (config, data, new NPC's, etc.)

3. Start login server and game server to make sure it's really working without errors

4. If everything is OK, dump your database to an SQL file

 

...and now for the "complicated" part...

 

5. If you had that on a separate PC, copy new rev on your server machine, along with your dumped SQL file

6. Make a separate DB on your server MySQL connection, like l2clean or whatever :)

7. Make sure you have altered server.properties and login.properties to match your internal / external IP

8. Stop your server (nasty !!!)

9. Go on Navicat to Tools -> Structure Syncronization

10. Left side -> (your connection name) -> (your new rev db)

11. Right side -> (your connection name) -> (your GS db)

12. Press "Compare" button

13. After compare has been done -> press "Run query" button

14. After successful completion go to Tools -> Data Syncronization

15. Left side -> (your connection name) -> (your GS db)

16. Right side -> (your connection name) -> (your new rev db)

17. Go "Advanced" and remove the mark from "Delete records"

 

Remark: BE SURE YOU REMOVED THAT MARK BEFORE STARTING !!!

 

18. Press "Preview" button

 

You will get 6 or 7 errors, tables which you should copy to a temporary DB FROM YOUR NEW REV DB and copy back after completion...

 

Normally this tables are:

boxaccess

clan_wars

pledge_skill_trees

posts

skill_spellbooks

topic

zone

 

19. If on "Preview" is everything OK then press "Start" to upgrade

 

BE SURE YOU HAVE COMPLETED POINT 17 BEFORE !!!

 

20. Now just dump SQL file of your old DB and copy your new DB instead

21. start your login server

22. start your game server

23. YOU'RE DONE !!!!!

 

It will take you longer in the first instance, with time will take less and less.

I do not want to be a big mouth but now, after 6 month, it's taking me about 10 minutes top...
