our site was initially built in sitecore XP, during XP we were loading boostrap.js file as part of the minified main.js file. Now the site is migrated from XP to XC.
Now in XC bootstrap-121.js file is available in sitecore media library folder, because of two bootstrap files conflict is happening, bootstrap components are failing on the site. If I remove the bootstrap-121.js file from sitecore media library functionality of the site is working fine and no more conflicts.
Is it safe to remove bootstrap file from sitecore media library as I am loading in main.js file, because bootstrap file in main.js is higher version(v3.3.7)...? What functionality will not work properly if I do this? What is the alternative to resolve this issue?
