How to convert quote tag

[Massl]

Hi, someone can help me to convert this MyBB quote

Code Select Expand

[quote='username' pid='4' dateline='1546585851']

to this SMF 2.1 quote

Code Select Expand

[quote author=username link=msg=4 date=1546585851]

In the converted forum there are hundreds of quotes and it is impossible to change them one by one.

Thanks

There is no good way in a database to do this. It needs a script to be written to go through and check each post one by one.
