Hi,
I have been facing an issue of migration becoming slower and slower as the data gets filled into the table. The versions are AX 2012 R3 and SQL 2016. When i perform the "Copy data to Target" step of DIXF for table CustQuotationTrans then only i feel the issue. For all other tables e.g. SalesQuotationTable, SalesQuotaitonLine and CustQuotationJour, its working very well.
When the table is empty and i start migration then it starts with very good speed of around 200 records per second but after around 100,000 records, it gets 100 records per second and then keeps on decreasing as the table gets filled on. There are around 50,00,000 records which i have to migrate.
I am, already running it in Batch with 8 tasks. So far, i have tried the below steps:
1) Table CustQuotationTrans has total 10 non-unique index. There was not any fragmentation issue on any index but still i rebuilt all indexes in the table but couldn't see any improvement.
2) I have tried disabling all indexes resulting which all index got deleted except Clustered index on RecId on SQL side but still couldn't see any improvement.
3) I made validate property NO on all relations on this table to disable all FKs but no improvement.
4) There is 12 GB memory allocated to this SQL server and 12 GB to another SQL server and still 8 GB free (DEV server: Total 32 GB) so there shouldn't be any memory issue too.
5) I have tried unchecking "Run business logic in Insert and Update" and "Run Business Validation" checkboxes but didn't make difference.
There must be surely something on the table side as the speed is getting deteriorating as the data is getting filled in table. Please suggest me any other solution which you think might work here.
Thanks
