How to reduce file size?

[mediamonster]

Sorry, I didn't understand your query here. What do you mean by 'file size' here? Is your database size 350mb long?

I mean the total file size in my cpanel. The WP migration plugin detects the size of my site database in my webhost is over 350MB.
Which is why it's unable to migrate my site to another host.

I don't understand the concept of using any plugin here. Just make a database backup through your cPanel and upload it in the new hosting. Its that simple. And moreover using any script plugin to migrate can damage your database while migrating.

And if I assume that your database only is up around 300mb (& your files of the site is of normal size). Then I will say that its way too much big for a 7 page site. You have to check your database table by table its the only option here. You must look for something that records the sessions or take the log records of bots or whatever coming to your site. Its highly likely that your database isn't able to get rid of the unused and irrelevant data records. Or, simple it isn't functioning properly.
