Problem For Rename Column With Keep Rows in Sequelize

[kasrakhamesi]

Hi,I have table with 5 column and 1000 row, I want rename second column from imageUrl to slug for example.
and I want sequelize do not delete row in old column and don't want create new column
only I want rename column with all rows.
but in this code

import { Post } from '/post/entities/post.entity';
import { Module } from '@nestjs/common';

import { SequelizeModule } from '@nestjs/sequelize';

@module({
imports: [
SequelizeModule.forRoot({
dialect: 'mysql',
host: host,
port: port,
username: user,
password: pass,
database: db,
models: [Post ],
logging: true,
autoLoadModels: true,
synchronize: true,
sync: { alter: true },
}),
],
exports: [SequelizeModule],
})
export class DatabaseModule {}

Sequelize create new column with name slug and remove imageUrl and the row in imageUrl not transfered to slug column and slug column have empty or null row.

if I change : sync: { alter: true } to sync: { alter: { drop : false }}, Sequelize create new column with name slug and imageUrl exist too.

if I change : sync: { alter: true } to sync: { force :true }, Sequelize delete all rows

so How can fix that ?
