Conversion Stages
Both the buffer copy and in-place conversions require similar conversion stages. The differences between the two methods are noted in each section:
Prepare the source database.
This includes archiving and deleting as many records as possible in the source database. This reduces the amount of data to be copied during a buffer copy. You then run reports for which you will run equivalent reports in the target database after the conversion in order to check the data. You should also preserve system-level custom data, such as user help and menus.
Create the target database.
For a buffer copy conversion, you create the target databases, but do not load the default system data. For in-place conversions, you create new administration and help databases, but not the production database. In addition, you need to migrate any Progress databases that are not already on Progress OpenEdge to the Progress OpenEdge schema.
In this guide, the directory where you install the target version is referred to as the TVInstallDir.
Run the MFG/UTIL Conversion
MFG/UTIL workflows are available for both conversion methods. In general, the workflows connect you to the appropriate databases, allow you to select the optional conversion programs, then dump or load data as required.
The OID value is then entered and the database is converted.
For more information on OID values, see the following section.
Install the clients
You can now install and configure your various clients as described in the installation guide for your database. In general, you must install client software, configure the database sets, compile the code, and generate new startup and shutdown scripts.
Additional manual setup is required for some programs, such as control settings or generalized codes. You then restore the custom default data, such as menus and user help.
