Z/vse to z/OS Conversion
Project Assessment
The Project Assessment service consists in analyzing the batch and
on-line applications to identify conversion requirements and potential
issues that may affect their conversion to z/OS.
After the customer has supplied a copy of the VSE applications (as
specified here),
LOGOS Computer Services LTD processes the inventory using
Prism-CS and other analytical
tools. The results of the analysis are reviewed to identify conversion
requirements and possible issues which are presented to the customer in a
written Conversion Specifications Document (CSD).
Note: The Project Assessment service is available to all
customers, whether they later on acquire a Prism-CS license
or not. For those customers who chose
Prism-CS to convert the
applications, we offer the option of producing a smaller CSD which omits
all the specifications already handled by the product; the resulting CSD
only presents the remaining issues that must be handled through
customisation.
Full z/VSE to z/OS Conversion
The Full Conversion is performed by conversion experts knowlegable
in z/VSE and z/OS operating systems and of PRISM-CS internals,
the conversion functions performed by GSF consultantst consists of the following:
KickStart
The KickStart helps Prism-CS Licensees get their
application conversion project off the ground faster by eliminating much
of the trial-and-error often associated with learning a new, complex
product.
All Prism-CS Licensees must
send a copy of their application inventory (source code, JCL, etc) to the
Prism-CS Support Center which analyses it and sets up a
custom procedure tailored to run a complete conversion process. The custom
procedure is then sent to the Prism-CS Licensee, along with
a list of conversion issues that have been identified during the
KickStart analysis process.
Inventory Validation
The Inventory Validation service helps companies considering a
conversion from VSE to MVS put their application inventory in order before
the application conversion project actually starts. The Inventory
Validation service consists of the following:
- Initial supply of the entire VSE application inventory (JCL,
programs, etc) to LOGOS Computer Services LTD four times on CD-ROM or via
the Internet.
- Build an automated procedure to transfer the VSE application
inventory to MVS and load various objects into partitioned data sets.
- Set up and run the
application
inventory component of the
Prism-CS to
cross-reference all the elements and produce lists of missing and
unreferenced elements
- Up to four additional supplies of the VSE application inventory for
processing. Each additional supply includes the corrections applied in
VSE to the application inventory, such as providing missing programs,
removing obsolete or duplicate elements, etc
- Identify most of the critical conversion issues that will have to be
resolved during the actual conversion project
Note: The Inventory Validation service is available to all
customers, whether they later on acquire a Prism-CS license
or not.
Customisation
Customisation relieves the Prism-CS Licensee
from having to dedicate internal resources to perform most customisation
tasks.
LOGOS Computer Services LTD offers its vast experience in designing and developing
plug-in modules and LCPs that process complex syntax elements and interact
efficiently with various components of the Prism-CS
software.
Quality Assurance Audits
QA Audits help Prism-CS Licensees assess the status of
their application conversion project and the quality of the converted
materials. At key points in the project, LOGOS Computer Services LTD analyses the
converted materials (programs, JCL, etc) for errors, omissions, and other
flaws, then suggests appropriate corrective action to prevent failures
during application testing.
Program Conversion
Program Conversion is performed for all programs which are
generally assembler, COBOL, PL/I or CICS. The customer supplies the source code,
COPY books and Macros to LOGOS Computer Services LTD which takes care of tailoring and
customising Prism-CS, and running it to convert the programs
from VSE to MVS, as well as compile and link-edit them. A customised
version of the Prism-CS product and program libraries is then shipped
electronically to the customer.
Besides program conversion from z/VSE to z/OS, we also can provide
optional services to translate programs from one language to another, as
listed here.

Switch-Over Assistance
On-site or off-site assistance from VSE/MVS migration experts is
available during and after the Switch-Over to help react to problems with
speed and accuracy. The Switch-Over is the most critical event in a
z/VSE to z/OS conversion project, when applications are converted for the last
time, production data is transferred for the last time, and production
goes live in the target environment, generally during a week-end. The
switch-over week-end itself and the days that follow are a time of intense
activity and nervousness, during which assistance from migration experts
can prove a valuable asset.
JCL Translation
The customer supplies its programs, VSE JCL, VSE catalog listings and
documentation for z/OS production standards to LOGOS Computer Services LTD. We then tailor
and customise Prism-CS until it generates good-quality MVS
JCL streams, and ship them electronically to the customer. The process is
repeated as many times as necessary until the customer is satisfied with
the result..
Custom Software Development
Development of conversion-related software, such as utility programs or
sub-routines. Languages available are Assembler, COBOL, PL/I or REXX.
