How to automatically create the custom migration scripts after recreating SSMA project?

Question

How to automatically create the custom data migration scripts after recreating SSMA project?
There is number of tables ( big tables with BLOBS)  which I want to set up automatically to be migrated with custom migration scripts (replacing e.g. attribute named "FILE" with "TO_BLOB('') AS FILE" ).
So the question is how to open MB file (I think that it should be standard db of some destktop RDBMS) ?

Hi Roman.Pokrovskij,
According
to your description, we can use SSMA tool to migrate data from one database (including Access, Oracle and so on) to SQL Server via GUI or the scripts. There is an example about migrating Access database to SQL Server via the
custom migration scripts, you can review refer to them.

<!-- Server definition for Sql server target server-->
<sql-server name="target_1">

<!--Schema Mapping-->

<!-- Convert schema -->
<!-- Example: Convert entire Schema (with all attributes)-->
<convert-schema object-name="$AccessDatabase$"
object-type="Databases"
conversion-report-overwrite="true"

report-errors="true" />
<!-- Synchronize target -->
<!-- Example: Synchronize target entire Database with all attributes-->
<synchronize-target object-name="$SQLServerDb$.dbo"
on-error="fail-script" />
<!-- Data Migration-->
<!--Example: Data Migration of all tables in the schema (with all attributes)-->
<migrate-data object-name="$AccessDatabase$.Tables"
object-type="category"
report-errors="true"
verbose="true"/>
</script-commands>
</ssma-script-file>
There is a similar scripts about migrating Oracle database to SQL Server, you can use powershell script to automatically run the console for scripts/variable files, saved in the specified folder. For more information, review the following
article.
