Can I use Outlook 2010 32-bit OST file when upgrading to Outlook 2016 64-bit without redownloading new OST

[Brad.Nelson GTF]

I need to upgrade Outlook 2010 32-bit to Outlook 2016 64-bit. We use Cache Mode and OST files, and want to verify it will use the same OST file after the upgrade as we have <g class="gr_ gr_139 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="139" id="139">alot</g> of users with large mailboxes and I <g class="gr_ gr_172 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="172" id="172">dont</g> want to redownload new OST files for bandwidth concern.

Will it use the OST file from the 32-bit outlook or create a new one?
