I have previously restored the database for the system, and while i tried to migrate through the django applicaion, the following error is thrown. What is the possible cause and how can we mitigate such cases. I guess the problem is with the existing table conflict, will it solve the issue by delete/dropping the conflicting tables.

I had the same problem and solved it by deleting the database a running the inital migrations again
I've recently upgraded form sqlite to postgresql for my django project.
In the past, whenever I've made a change to a model, I simply ran makemigrations and then the migrate command. No issues.
Now, with posgresql, when I make the INITIAL makemigrations/migrate, it works fine as per usual, but if I make a change to a model and then run makemigrations and then migrate, on the 'migrate' command, the system tries to apply the initial migration again and returns an error saying the table already exist (which it does).
How can I run migrate without the system trying to remigrate migrations that have already been migrated?
Thanks!

Looks like i have to run python manage.py migrate --fake-initial to ignore initial migrations.
I use to run my website on my laptop and its database was Sqlite, recently I wanted to transfer it to DigitalOcean and I changed its database to Postgresql, but when I migrate I encounters with some problems.

Any help is highly appreciated. Thanks in advance.
The first error might be because you tried to set unique=True for the TextField. This is not possible for MySQL, as noted in the docs.
The second error is because you are trying to create an index that already exists. This could be because you already ran the migration and it failed part way through. MySQL does not run schema changes in a transaction, so changes aren't rolled back if they fail. You could try dropping the index manually, or, if this is a new project, it might be easier to drop the database and start again.
