In one of my project i have used Asp.net membership provider and there is some data on production environment.Now i need to to migrate that DB with SQL Azure.
I have used SQLAzureMW tool to migrate that and that tool has done proper migration except aspnet_user table's data and some of SPs and i have skip that table manually at time of final step on that tool
When i have looked in to data then aspnet_users table's data missing!
I have also read about New script for SQL Azure but i think that is for to create from scratch, i also heard about Universal Provider but confused in that.
As per my requirement what steps i need to follow to migrate existing sql db to windows azure sql db(WASD) with data and considering this what would be impact of that on application?
Note: Session State is also being managed using SQL provider here
Update
Again i have tried it with SQLAzureMW tool and this time i noticed that due to default collation type some of Sps were missing so i have run that manually as per this link
However still i need to make sure would there be any issue regarding session state Or other thing as i have migrate it's from existing db to WASD?
the SQLAzureMW tool show any message that you skip?
I have had many problems with this tool, but finally I could did everything with it. I would try creating first time Data Schema Only, and after copying the Data. Maybe you should use also DROP and CREATE option when generating the script, if the old data can't be overwrite. I hope this helps!

We are building data migration pipeline using Azure data factory (ADF). We are transferring data from one CosmosDb instance to another. We plan to enable dual writes, so that we write to both the databases before migration begins to ensure that during migration if any data point changes both the databases get the most updated data. However, In ADF there is only Insert or upsert options available. Our case is on Insert if it gets 'conflict' continue and fail the pipeline. Can anyone give any pointers on how to achieve that in ADF?
Other option would be to create our own custom tool using CosmosDb libraries to transfer data.
If you are doing a live migration ADF is not the right tool to use as this is intended for offline migrations. If you are migrating from one Cosmos DB account to another your best option is to use the Cosmos DB Live Data Migrator.
This tool also provides dead letter support as well which is another requirement you have.
I have a backup file that came from Server A and I copied that .bak files into my local and setup that DB into my Sql Server Management Studio. Now After setting it up I deployed it in Azure Sql Database. But now there were change in the Data in Server A because it's still being used, so I need to get all those changes to the Azure SQL Database that I just deployed. How am I going to do that?
Note: I'm using Azure for my server and I have a local copy of Server A database. So basically in terms of data and structure my local and the previous Server A db is the same. But after a few days Server A data is now updated and my local DB is still the same as when I just backup the db in Server A.
How can I update the DB in Azure to take all the changes in Server A and deploy it in Azure?
You've got a few choices. It's just about migrating data. It's also a question of which data you're going to migrate. Let's say it's a neat, complete replacement. Then, I'd suggest looking at the bacpac mechanism. That's a way to export a database, it's structure and data, then import it into a new location. This is one mechanism of moving to Azure.
If you can't simply replace everything, you need to look at other options. First, there's SSIS. You can build a pipeline to move the data you need. There's also export and import through sqlcmd, which can connect to Azure SQL Database. You can also look to a third party tool like Redgate SQL Data Compare as a way to pick and choose the data that gets moved. There are a whole bunch of other possible Extract/Transform/Load (ETL) tools out there that can help.
Do you want to sync schema changes as well as Data change or just Data? If it is just Data then the best service to be used would be Azure Data Migration Service, where this service can help you copy the delta with respect to Data to Azure incrementally, both is online and offline manner and you can also decide on the schedule.
My requirements are as below :
Move 3 SAP local databases to 3 Azure SQL DB.
Then Sync daily transactions or data to azure every night. If transactions of local DB are already exists in azure, update process will do on these transactions if not insert process will do.
Local systems will not stop after moving to azure. They will still goes about 6 months.
Note :
We are not compatible with Azure Data Sync process because of it's
limitations - only support 500 tables, can't sync no primary keys
table, no views and no procedure. It also increase database size on
both(local and azure).
Azure Data Factory Pipeline can fulfill my requirements but I have
to create pipeline and procedure manually for each table. (SAP has
over 2000 tables, not good for me)
We don't use azure VM and Manage Instance
Can you guide me the best solution to move and sync? I am new to azure.
Thanks all.
Since you mentioned that ADF basically meets your needs, I will try to start from ADF. Actually,you don't need to manually create each table one by one.The creation could be done in the ADF sdk or powershell script or REST api. Please refer to the official document:https://learn.microsoft.com/en-us/azure/data-factory/
So,if you could get the list of SAP table names(i found this thread:https://answers.sap.com/questions/7375575/how-to-get-all-the-table-names.html) ,you could loop the list and execute the codes to create pipelines in the batch.Only table name property need to be set.
I have an Oracle DB with data that I need to load and transform into an Azure SQL Database. I have no control over either the DB nor the application that updates its data.
I'm looking at Azure Data Factory, but I really need data changes in Oracle to be reflected as near to real-time as possible.
I would appreciate any suggestions / insights.
Is ADF the correct tool for the job? If so, what is a good approach to use? If not suitable, what should I consider using instead?
For real-time you don't really want an ELT/ETL tool like ADF. Consider a replication agent like Attunity or (gulp at the licensing costs) GoldenGate.
I don't think Data Factory is not good for you. Yes you can copy data from Oracle to Azure SQL database with it. But like #Thiago Custodio said, we need need to do it to each table you have. That's too complicated.
Just reference: Copy data from and to Oracle by using Azure Data Factory.
As you said, you really need data changes in Oracle to be reflected as near to real-time as possible.
The migration/copy time must be very short. Then the data in Oracle and Azure SQL database could be same before the Oracle data changed next time. I searched a lot and didn't find any real-time copy tools. Actually, I think you want the copy could be something like 'data sync'.
I found this link Sync Oracle Database with SQL Azure, hope it could give some good ideas for you.
About the data migration or copy, You can using bellow ways:
SQL Server Migration Assistant for Oracle (OracleToSQL)
Azure Database Migration Service (DMS)
Reference tutorial:
Migrating Oracle Databases to SQL Server (OracleToSQL): SQL Server Migration Assistant (SSMA) for Oracle is a comprehensive environment that helps you quickly migrate Oracle databases to Azure SQL database.
How to migrate Oracle to Azure SQL Database with minimum downtime:
Hope this helps.
For the record, we went with a product named QLik Replicate (aka Attunity) and it is working very well!
I am sort of new to MVC, as it has been a few years since I used it.
I created a new site with individual passwords option selected. The wizard created a local database for me, and uses code first to create the database and table for identity management.
I tried changing the connection string to be the same as my entityframework connection string, and that did nothing, even after I ran the app. In fact, it seemed to have no effect, and somehow it still had access to the local db version.
How do I point the existing code first tables to build a new set of tables on my existing azure database, and then use those tables going forward?
