You CANNOT backup 1.3 and restore to 3.14
That’s why I am trying to my latest backup take from v1.3.0 and restore it 3.14
NO. You cannot do this.
There are too many changes in the database. It will break your RocketChat.
You need to CAREFULLY upgrade your RocketChat 1.3.0 to 3.14
First you must Backup your version 1.3.x and make sure you know where the data is.
Next you must upgrade your 1.3.x installation. I suggest you do it in steps like this with a separate backup between each step.
1.3 > 1.3.2 → 2.0.1 → 2.4.13 → 3.0.12 → 3.9.7-> 3.14
So where is your backup from 1.3.0 ? Did you test the backup was OK?
Note - you will also need to convert your DB from mmap to wiredtiger.
Here is how to do this and how to backup:
