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.
