### Description

I want to upgrade mongo from 4.4 to 5 to 6 and tried different ways, but none leads to success.  
After the mongo update:

1. apt upgrade mongo4-\>mongo5
2. remove mongo 4 and install mongo 5

rocketchat won´t start anymore.  
What is the best and preferred way to do this?

Hi, please refer to MongoDB’s official documentation for this.

Hi, did you forget re-initiate replica?  
This is what I did:

1. stop rocket.chat server
2. backup mongo database  
mongodump —out mongodump001
3. backup /etc/mongod.conf
4. purge old pkgs  
sudo apt-get purge mongodb-org\*
5. delete old mongo files  
sudo rm -rf /var/lib/mongodb
6. install mongodb 5.x  
remove old apt.source for 4.4  
add new apt.source for 5.0  
sudo apt-get update  
sudo apt-get install mongodb-org
7. restore /etc/mongod.conf
8. restart mongo and check running  
(if not, remove “fork: true” line)
9. initiate rs01 replica  
mongo -eval “printjson(rs.initiate())”
10. restore mongo database  
mongorestore mongodump001 —drop
11. restart mongo
12. start rocketchat server
13. clear cookies for the server on browser
14. connect to the server

I am not a mongo/rocketchat expert. So I am not sure if this is the best procedure.

Hi cawcaw,  
somewhat later, but this saved my nerves.  
many thanks, the rs.initiate was the solution…
