Database replication/merge

downsouth

Hi Y'all,
I would enormously appreciate help with the following Axapta 3.0 setup. I would like to merge an Axapta 3.0 database complete with settings and data as well as record ID's to another database in the same SQL 2005 instance. I am aware that Axapta 4.0 has made the problem easier to cope with but I cannot at this point upgrade.
My understanding thus far of the record ID's is that they are assigned on the inital database, sequentially, without checking for available (free) ID's, to compound the problem ID's are controlled Globally ,not per table, which could result in duplicate records or missing(dropped) records in the replicated database.
The solution in my opinion would be to create a table on the replicated/merged database that would monitor/synchronise the records on both the databases, or have the replication "filter" through a custom process.
The merge will be once off and exist thereafter only in the new location, my research thus far has recommended a snapshot merge.
Please post a pedantic step for step guide if you are aware of a solution.

Thanks in advance,
Downsouth
