Day 678 - New Data Migration Strategy

The data migration strategy has changed again.
Now we will have 2 phases, and the first one will be slitted in two, making it an incremental data migration.
In phase One A, we will migrate clients and a big part of insurances that are wither active or that have accidents on it.
The phase One B, we will migrate the remaining insurances that are wither active or that have accidents on it, and everything related with those insurances.
And in the final phase, phase Two, we will migrate everything else, commonly known as historical data.

This will force me to implement control mechanisms in order to know which data will go in which phase. We will test this mechanism within a week or so in another big data migration.

Day 671 - Murphy Was Nicer

The data migration over this last weekend worked better.
But Murphy's law still stroke back, but in a lighter way.
For the next two weeks we will have lots of work fixing everything that went wrong in this past two weekends.

Day 667 - Not bad Results

We actually had very good results in data that was loaded property into GIS.
Since most of the problems occurred outside GIS, the data we sent into it had an overall success above 90%, and many over 99%, which is quite good considering all the problems we had.
The tests performed over that migrated data are also satisfying, which is quite good.

Day 664 - Another Data Migration Try

This weekend data migration was stroke hard by Murphy's law.
It was terrible. It really seemed that everything that could go wrong, went wrong.
Many of the failed data loads will be repeated during the week.
And in the next weekend we'll try again with another data set.

Day 660 - "Go" Decision For Half Data Migration

This situation and the pressure people is getting to make things fast it's totally unbelievable. This has lead management into splitting the data migration by the next two weekends. Thus, the next weekend it will migrate customers, insurance claims and invoices. But only if they are not involved in some kind of accident, otherwise it's migration will happen in the other weekend.

This will allow the integration test teams to perform preliminary validations and I also believe it will be great because I know that the entire data migration does not integrate into GIS during a single weekend with the current AS/400 system configuration.

Meanwhile, the software patches continues to give us problems.

Day 658 - Next Qualification Migration In Risk

According to planing, in the next weekend a new data migration should occur in the qualification environment. But unfortunately there's so many problems and change requests happening that the mapping is very unstable within a few days from the beginning of the data migration.

This next weekend data migration is in risk, and this is critical for the entire project, since the data migration is in the project critical path.

Management still doesn't know if it's a "go" or a "no go", that decision will be taken late this week.

Day 655 - Under Pressure

This past week the team has been reinforced with one extra person. This was critical because we had 4% of change requests during this past 5 week. He have implemented and tested 146 change requests, including new mapping tables and claim mappings that should be stable for weeks now.

This kind of instability is making the entire team under great pressure beacause within one week, a new data migration will be performed to qualification environment.
