TFS 2012 upgrade to TFS 2015: Database sync from TFS2012 to TFS 2015 -

-

i upgrading tfs 2012 tfs 2015 in new hardware new configuration. stratagy copy db , upgrade them , after sometime switch on new tfs 2015.

there time between actual switchover of tfs 2012 2015, (in case days). approach taken because cannot have production downtime of tfs.

now time (days) taken, there lot of new data inserted in old tfs 2012 database. how migrate new additional data new tfs 2015.

i having question because tfs 2015 versus tfs 2012 there table changes, taken care tfs upgrade. if want insert tfs2012 data tfs 2015 there issues? or there better approach upgrade?

you should test migration understand how long upgrade take.

once have information need take tfs offline upgrade. quick process can done in evening or weekend.

the idea can't take server offline regular maintenance faulty 1 , unachievable.

you can't insert data database ss break tfs.

syncing data after fact prove difficult , time consuming.
